The effect of pendant group structure on the thermoresponsive properties of N-substituted polyesters

Synthetic polymers exhibiting reversible lower critical solution temperature (LCST), such as poly(N-iso-propylacrylamide) (PNIPAM), are intriguing materials with various potential applications. We recently developed a new class of biodegradable thermoresponsive polyesters (TR-PEs) based on N-substituted diol monomers. TR-PEs exhibited reversible cloud point temperatures (Tcp) between 0-50 degrees C and were shown to be non-cytotoxic. The synthesis of N-substituted diols and TR-PEs is highly modular, allowing for a wide variety of possible homo-and copolyesters. In this work, we report the synthesis and characterization of 20 homopolyesters in order to better understand the structure-property relationship of TR-PEs. UV-vis spectroscopy showed that the Tcp of TR-PEs was highly dependent on pendant group structure, such as secondary or tertiary amides, cyclic and linear groups, and substitution of oxygen atoms. Structure-Tcp analysis provides a correlation between Tcp and the number of heteroatoms relative to the number of carbon atoms in the pendant group thereby providing a rationale for the design of thermoresponsive polyesters with desired Tcp values. To demonstrate the expanded tunability of the TR-PE system, copolyesters bearing covalently attached ibuprofen were synthesized and shown to exhibit LCST behavior dependent on comonomer hydrophilicity.

Multigram-scale flow synthesis of the chiral key intermediate of (-)-paroxetine enabled by solvent-free heterogeneous organocatalysis

The catalytic enantioselective synthesis of the chiral key intermediate of the antidepressant (-)-paroxetine is demonstrated as a continuous flow process on multi-gram scale. The critical step is a solvent-free organocatalytic conjugate addition followed by a telescoped reductive amination-lactamization-amide/ester reduction sequence. Due to the efficient heterogeneous catalysts and the solvent-free or highly concentrated conditions applied, the flow method offers key advances in terms of productivity and sustainability compared to earlier batch approaches.

Synthesis of matrinic amide derivatives containing 1,3,4-thiadiazole scaffold as insecticidal/acaricidal agents

In continuation of our program aimed at the development of natural product-based pesticidal agents, a series of matrinic amide derivatives containing 1,3,4-thiadiazole scaffold were prepared, and their insecticidal and acaricidal activities were evaluated against Mythimna separata and Tetranychus cinnabarinus. Some compounds exhibited potent insecticidal and acaricidal activities. It suggested that R-1 as a nitro group and R-2 as a fluorine atom, were important for the insecticidal activity; R-1 as the electron-donating groups and R-2 as the methyl group, were necessary for the acaricidal activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 92-50-2. Formula: C10H15NO.

Rh-Catalyzed Decarbonylative Cross-Coupling between o-Carboranes and Twisted Amides: A Regioselective, Additive-Free, and Concise Late-Stage Carboranylation

The convenient cross-coupling of sp(2) or sp(3) carbons with a specific boron vertex on carborane cage represents significant synthetic values and insurmountable challenges. In this work, we report an Rh-catalyzed reaction between o-carborane and N-acyl-glutarimides to construct various B-cage-C bonds. Under the optimized condition, the removable imine directing group (DG) leads to B(3)- or B(3,6)-C couplings, while the pyridyl DG leads to B(3,5)-Ar coupling. In particular, an unexpected rearrangement of amide reagent is observed in pyridyl directed B(4)-C(sp(3)) formation. This scalable protocol has many advantages, including easy access, the use of cheap and widely available coupling agents, no requirement of an external ligand, base or oxidant, high efficiency, and a broad substrate scope. Leveraging the Rh-I dimer and twisted amides, this method enables straightforward access to diversely substituted and therapeutically important carborane derivatives at boron site, and provides a highly valuable vista for carborane-based drug screening.

A graphene hybrid supramolecular hydrogel with high stretchability, self-healable and photothermally responsive properties for wound healing

Wound healing is a ubiquitous healthcare problem in clinical wound management. In this paper, the fabrication of a graphene hybrid supramolecular hydrogel (GS hydrogel) for wound dressing applications is demonstrated. The hydrogel is composed of two components, including N-acryloyl glycinamide (NAGA) as the scaffold and graphene as the photothermally responsive active site for photothermal therapy. Based on the multiple hydrogen bonds between the dual amide motifs in the side chain of N-acryloyl glycinamide, the hydrogel exhibits high tensile strength (approximate to 1.7 MPa), good stretchability (approximate to 400%) and self-recoverability. In addition, the GS hydrogel shows excellent antibacterial activity towards methicillin-resistant Staphylococcus aureus (MRSA), benefiting from the addition of graphene that possesses great photothermal transition activity (approximate to 85%). Significantly, in vivo animal experiments also demonstrated that the GS hydrogel effectively accelerates the wound healing processes by eradicating microbes, promoting collagen deposition and angiogenesis. In summary, this GS hydrogel demonstrates excellent mechanical performance, photothermal antimicrobial activity, and promotes skin tissue regeneration, and so has great application potential as a promising wound dressing material in clinical use.

Competition between the donor and acceptor hydrogen bonds of the threads in the formation of [2] rotaxanes by clipping reaction

The synthesis of benzylic amide [2] rotaxanes using 1,2-bis(aminocarbonyl-(1′-tert-butyl-1H-pyrazole-[3′] 5′-yl))-ethanes as templates is reported. These templates are equipped with tert-butyl pyrazole-based stoppers and have donor (N-H) and acceptor (C=O) hydrogen bond groups. The synthesis of [2] rotaxanes has been shown to be highly dependent on the tert-butylpyrazole stoppers. While the thread with 10,30-disubstituted pyrazoles as stopper units was shown to be an excellent template for the synthesis of [2] rotaxanes, the thread with 1′,5′-disubstituted pyrazoles as stopper units did not yield the expected [2] rotaxane. The structure of the synthesized [2] rotaxanes was characterized using NMR experiments and X-ray diffraction, with the latter showing that the macrocycle adopts a distorted chair conformation. An in-depth study of the isolated thread’s X-ray structures and concentration-dependent NMR experiments seem to explain the dependence of the rotaxane formation on the substitution pattern of the thread’s pyrazole stoppers.

Nickel-catalyzed reductive defunctionalization of esters and amides to aromatic hydrocarbons

The removal of ester and amide groups is of fundamental significance in organic syntheses. Under noncatalytic conditions, hydride sources are chiefly used for their reduction. Recently developed Ni-catalyzed one-pot reductive activation of esters and amides followed by tandem C-CO bond cleavage-decarbonylation facilitates their cleavage to aromatic hydrocarbons. Isolation and characterization of key reaction intermediates provide insight into this acyl C-O bond activation pathway.

Evaluation of vinburnine in pharmaceuticals by smart spectrophotometric methods; full stability study

Vinburnine (VNB) is a vinca alkaloid used as a vasodilator to enhance cerebral circulatory insufficiency. It is a cyclic amide containing drug which is expected to be sensitive to hydrolytic degradation. The degradation profile of VNB was studied in this work following ICH recommendations for stability study. The drug was sensitive only to degradation with NaOH with the formation of the carboxylic acid derivative, identified by IR and H-1 NMR analyses as 2-((1S,12bS)-1-ethyl-1,2,3,4,6,7,12,12b-octahydroindolo[2,3-a] quinolizin-1-yl) acetic acid, (DEG). In this study five simple, smart and univariate stability indicating spectrophotometric methods were developed and validated for simultaneous determination of VNB and DEG for the first time. The developed methods include; Dual Wavelength Method (DWM), Dual Wavelength Resolution Method (DWRM), Factorized Absorbance Difference Method (FADM), Advanced Absorbance Subtraction Method (AASM), and Derivative Amplitude Factor Method (DAFM). These methods were capable of determination of VNB and DEG over the ranges of 1-30 and 3-50 mu g/mL, respectively. The proposed methods were simple, smart, specific, and could be applied for analyzing synthetic mixtures of VNB and DEG and were successfully applied for determination of the drug in commercially available capsules. The obtained results of these methods were statistically compared with the reported HPLC one using student’s-t and F- tests, where no significant difference was observed. Validation of the developed methods was applied according to ICH recommendations and all the results were within the acceptable limits. Published by Elsevier B.V.

Photocatalytic amidation and esterification with perfluoroalkyl iodide

The successful generation of perfluoroalkyl radicals (R-f) through photoredox catalysis has inspired us to investigate the preparation of various organofluorine species. In this work, visible light-induced photocatalytic reactions for the preparation of perfluoroalkyl amides and esters from the corresponding amines and alcohols using different types of triplet emitters as photocatalysts have been studied. The effects of the excited-state characteristics and redox potentials of the photocatalysts have been elucidated. Under optimized reaction conditions, these reactions can be performed successfully with different types of amines or alcohols and perfluoroalkyl iodides. Detailed mechanistic studies based on emission quenching experiments have been performed to study the photocatalytic cycles as well as the role of the different reagents. The proposed mechanism has also been examined by DFT calculations.
