Advances in amide and thioamide assisted C(sp(3))-H functionalization

C-H activation is gaining substantial attention from synthetic and process chemists in recent years. Regio- and stereo-selective C-H functionalization particularly facilitated by carboxylic acids and derivatives as directing groups has been progressing to an extent that this transformation could be conceived as one of the steps to assemble molecules in modern retrosynthetic analysis. This digest paper covers the most recent developments in C(sp(3))-H functionalization using carboxylic acid derivatives such as amides or thioamides as a directing group and highlights new reaction discoveries and applications. The content of this review is organized based on the types of directing groups and the mechanism by which the C(sp(3))-H bond is believed to be activated. (C) 2019 Elsevier Ltd. All rights reserved.

Carbonate-Catalyzed Room-Temperature Selective Reduction of Biomass-Derived 5-Hydroxymethylfurfural into 2,5-Bis(hydroxymethyl)furan

Catalytic reduction of 5-hydroxymethylfurfural (HMF), deemed as one of the key bio-based platform compounds, is a very promising pathway for the upgrading of biomass to biofuels and value-added chemicals. Conventional hydrogenation of HMF is mainly conducted over precious metal catalysts with high-pressure hydrogen. Here, a highly active, sustainable, and facile catalytic system composed of K2CO3, Ph2SiH2, and bio-based solvent 2-methyltetrahydrofuran (MTHF) was developed to be efficient for the reduction of HMF. At a low temperature of 25 degrees C, HMF could be completely converted to 2,5-bis(hydroxymethyl)furan (BHMF) in a good yield of 94% after 2 h. Moreover, a plausible reaction mechanism was speculated, where siloxane in situ formed via hydrosilylation was found to be the key species responsible for the high reactivity.

Clarifying the dehydrogenation pathway of catalysed Li-4(NH2)(3)BH4-LiH composites

The effect of different metal oxides (Co3O4 and NiO) on the dehydrogenation reaction pathways of the Li-4(NH2)(3)BH4-LiH composite was investigated. The additives were reduced to metallic species i.e. Co and Ni which act as catalysts by breaking the B-H bonds in the Li-B-N-H compounds. The onset decomposition temperature was lowered by 32 degrees C for the Ni-catalysed sample, which released 8.8 wt% hydrogen below 275 degrees C. It was demonstrated that the decomposition of the doped composite followed a mechanism via LiNH2 and Li3BN2 formation as the end product with a strong reduction of NH3 emission. The sample could be partially re-hydrogenated (similar to 1.5 wt%) due to lithium imide/amide transformation. To understand the role of LiH, Li-4(NH2)(3)BH4-LiH-NiO and Li-4(NH2)(3)BH4-NiO composites were compared. The absence of LiH as a reactant forced the system to follow another path, which involved the formation of an intermediate phase of composition Li3BN2H2 at the early stages of dehydrogenation and the end products LiNH2 and monoclinic Li3BN2. We provided evidence for the interaction between NiO and LiNH2 during heating and proposed that the presence of Li facilitates a NHx-rich environment and the Ni catalyst mediates the electron transfer to promote NHx coupling.

Synthetic oleanane triterpenoids enhance blood brain barrier integrity and improve survival in experimental cerebral malaria

Background: Cerebral malaria (CM) is a severe complication of Plasmodium falciparum infection associated with high mortality and neurocognitive impairment in survivors. New anti-malarials and host-based adjunctive therapy may improve clinical outcome in CM. Synthetic oleanane triterpenoid (SO) compounds have shown efficacy in the treatment of diseases where inflammation and oxidative stress contribute to pathogenesis. Methods: A derivative of the SO 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid (CDDO), CDDO-ethyl amide (CDDO-EA) was investigated for the treatment of severe malaria in a pre-clinical model. CDDO-EA was evaluated in vivo as a monotherapy as well as adjunctive therapy with parenteral artesunate in the Plasmodium berghei strain ANKA experimental cerebral malaria (ECM) model. Results: CDDO-EA alone improved outcome in ECM and, given as adjunctive therapy in combination with artesunate, it significantly improved outcome over artesunate alone (p = 0.009). Improved survival was associated with reduced inflammation, enhanced endothelial stability and blood-brain barrier integrity. Survival was improved even when administered late in the disease course after the onset of neurological symptoms. Conclusions: These results indicate that SO are a new class of immunomodulatory drugs and support further studies investigating this class of agents as potential adjunctive therapy for severe malaria.

The Gastric Ganglion of Octopus vulgaris: Preliminary Characterization of Gene- and Putative Neurochemical-Complexity, and the Effect of Aggregata octopiana Digestive Tract Infection on Gene Expression

The gastric ganglion is the largest visceral ganglion in cephalopods. It is connected to the brain and is implicated in regulation of digestive tract functions. Here we have investigated the neurochemical complexity (through in silico gene expression analysis and immunohistochemistry) of the gastric ganglion in Octopus vulgaris and tested whether the expression of a selected number of genes was influenced by the magnitude of digestive tract parasitic infection by Aggregata octopiana. Novel evidence was obtained for putative peptide and non-peptide neurotransmitters in the gastric ganglion: cephalotocin, corticotrophin releasing factor, FMRFamide, gamma amino butyric acid, 5-hydroxytryptamine, molluscan insulin-related peptide 3, peptide PRQFV-amide, and tachykinin-related peptide. Receptors for cholecystokinin(A) and cholecystokinin(B), and orexin(2) were also identified in this context for the first time. We report evidence for acetylcholine, dopamine, noradrenaline, octopamine, small cardioactive peptide related peptide, and receptors for cephalotocin and octopressin, confirming previous publications. The effects of Aggregata observed here extend those previously described by showing effects on the gastric ganglion; in animals with a higher level of infection, genes implicated in inflammation (NF kappa B, fascin, serpinB10 and the toll-like 3 receptor) increased their relative expression, but TNF-alpha gene expression was lower as was expression of other genes implicated in oxidative stress (i.e., superoxide dismutase, peroxiredoxin 6, and glutathione peroxidase). Elevated Aggregata levels in the octopuses corresponded to an increase in the expression of the cholecystokinin(A) receptor and the small cardioactive peptide-related peptide. In contrast, we observed decreased relative expression of cephalotocin, dopamine beta-hydroxylase, peptide PRQFV-amide, and tachykinin-related peptide genes. A discussion is provided on (i) potential roles of the various molecules in food intake regulation and digestive tract motility control and (ii) the difference in relative gene expression in the gastric ganglion in octopus with relatively high and low parasitic loads and the similarities to changes in the enteric innervation of mammals with digestive tract parasites. Our results provide additional data to the described neurochemical complexity of O. vulgaris gastric ganglion.

Polysuccinimide and its derivatives: Degradable and water soluble polymers (review)

Interest for water soluble polymers which show biocompatibility and degradability is growing due to their potential applications in medical sciences. Polysuccinimide (PSI), commonly synthesized through thermal polymerization, is a polyimide precursor for the production of such biocompatible and degradable polymers namely polyaspartic acid and various polyaspartamides. Polyaspartic acid is usually obtained by hydrolysis of PSI while polyaspartamide is produced by ring opening of PSI using a nucleophilic reagent. The presence of amide linkages in these polymers gives them peptide-like structures which is prone to hydrolysis and subsequent degradation. These derivatives could be potential substitutes for different polyamino acids in many medical applications. This review compiles the works carried out on developing polysuccinimide and its derivatives as well as the main synthetic routs and characterization methods.

Discovery and evaluation of Ca(v)3.2-selective T-type calcium channel blockers

We identified and characterized a series of pyrrole amides as potent, selective Ca(v)3.2-blockers. This series culminated with the identification of pyrrole amides 13b and 26d, with excellent potencies and/or selectivities toward the Ca(v)3.1- and Ca(v)3.3-channels. These compounds display poor physicochemical and DMPK properties, making their use difficult for in vivo applications. Nevertheless, they are well-suited for in vitro studies. (C) 2017 Elsevier Ltd.

Niclosamide and dichlorphenamide: new and effective corrosion inhibitors for carbon steel in 1M HCl solution

This research demonstrates the effect of some amide compounds (1 and 2) as corrosion inhibitors on C-steel in 1.0 M of hydrochloric solutions utilizing mass reduction studies, electrochemical [potentiodynamic (PP), AC impedance measurements (EIS), electrochemical frequency modulation] techniques, and surface checks were used to illustrate the importance of amide compounds to the corrosion protection process of C-steel. The tests displayed that the inhibition efficiency (IE%) augmented with increase in amide dose but reduced with growth of temperature. The highest inhibition efficiency is 99% for compound (1) and 98.8% for compound (2) at maximum dose tested (50 mu M) by polarization method. PP data show that these compounds affect both cathodic and anodic processes (i.e. mixed type) and were adsorption on the carbon steel obeying Langmuir adsorption isotherm. The EIS results indicate that the changes in impedance parameters are related to the adsorption of amides on the alloy surface. Scanning of electron microscopy, energy transmitted X-ray-Atomic force microscopy studied the morphology of inhibited C-steel. [GRAPHICS] .

Mechanically strong plant oil-derived thermoplastic polymers prepared via cellulose graft strategy

The design of polymers from renewable plant oils is gaining more attention within sustainable development. Most plant oils based thermoplastic polymers exhibit poor mechanical properties. In this paper, we reported the mechanically strong cellulose-graft-soybean oil copolymers, which combined two natural biomasses in one. The soybean oil-based monomers with secondary amide groups (SOM1) and tertiary amide groups (SOM2) were prepared and copolymerized. The mechanical properties of the P(SOMl-co-SOM2) copolymers were investigated. Cellulose-g-P(SOMl-co-SOM2) copolymers with 0.5 wt% cellulose were prepared via atom radical transfer polymerization. FT-IR, H-1 NMR, and TGA measurements demonstrated that the Cellulose-g-P(SOMl-co-SOM2) copolymers were successfully prepared. Tensile test results demonstrated that the mechanical properties of the as-prepared Cellulose-g-P(SOMl-co-SOM2) copolymers were superior to the linear P(SOMl-co-SOM2) copolymers.

Nickel(II) Cyclen Complexes Bearing Ancillary Amide Appendages for the Electrocatalytic Reduction of CO2

Substituted cyclen complexes of nickel(II) containing either one or two pendant amide groups were prepared as potential electrocatalysts for the reduction of CO2 to CO. Four complexes bearing two amide substituents with either tert-butyl ([Ni(DMCy2tBu)](PF6)(2)), mesityl ([Ni-(DMCy2Mes)](PF6)(2)), 3,5-bis(triffuoromethyl)phenyl ([Ni-(DMCy2CF3)](PF6)(2)), or pentafluorophenyl ([Ni-(DMCy2C6F5)](PF6)) groups were all easily prepared and isolated without the need for column chromatography. Similarly, two other nickel(II) cyclen derivatives containing a single mesityl substituted amide pendant ([Ni(DMCyMes(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl) were also prepared. X-ray crystal structures were obtained for each of these complexes and show that the pendant amides are bound to the nickel(II) center at the core of the cyclen complexes. The amides coordinate to the central metal via either the amide oxygen or amide nitrogen atoms depending on the electronic properties of the amide group. The ability of each of the six complexes to electrochemically reduce CO2 was surveyed by voltammetric and controlled potential electrolysis (CPE) experiments. As the functional groups on the amide arms become more electron donating, the ability of the complexes to electrochemically activate CO2 improves. Of the four complexes containing two amide groups, [Ni(DMCy2tBu)](PF6)(2) and [Ni(DMCy2Mes)](PF6)(2) show the highest Faradaic efficiencies and current densities for CO production in contrast to homologues that contain amides with fluorinated ancillary groups ([Ni(DMCy2CF3)](PF6)(2) and [Ni(DMCy2C6F5)](PF6)). Ultimately, of the six cyclen complexes studied, the two that contain only a single pendant amide ([Ni(DMCyMes)(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl) proved to be the most active and efficient architectures for the electrocatalytic reduction of CO2 to CO. Both the [Ni(DMCyMes)(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl complexes were stable under the conditions of electrocatalysis and promoted the reduction of CO2 to CO with Faradaic efficiencies as high as 80%.
