Beckmann rearrangement of ketoximes promoted by cyanuric chloride and dimethyl sulfoxide under a mild condition

Synthesis of amides via Beckmann rearrangement of ketoximes promoted by cyanuric chloride (TCT)/DMSO under mild conditions has been reported. Conditions of the Beckmann rearrangement, e.g., solvents, the ratios of TCT/DMSO, and the temperature, were investigated using diphenylmethanone oxime as a substrate. The optimized conditions were adopted to afford fourteen amides with yields ranging from 20% to 99%. A plausible mechanism involving an active dimethyl alkoxysulfonium intermediate was proposed according to the mass spectrometry analysis. To our best knowledge, this is the first case of study on Beckmann rearrangement of ketoximes promoted by TCT/DMSO under a mild condition to afford amides efficiently. (C) 2020 Elsevier Ltd.

The structures of these compounds confirmed by NMR, FTIR and X-ray analysis. According to X-ray analysis data the lengths of coordination bonds C=O -> Si in studied compounds are 1.969, 2.000 and 2.176 angstrom respectively. The lengths of Si-F-ax. comprise 1.686, 1.661 and 1.632 angstrom respectively. QTAIM analysis was used to estimate the energy of co-ordination bond C=O -> Si in these amides. Calculated data shows that its value varies within 14-30 kcal/mol that close to the energy of co-ordination bond in some metalcomplexes. (C) 2020 Elsevier B.V. All rights reserved.

Iron-Catalyzed Directed Alkylation of Carboxamides with Olefins via a Carbometalation Pathway

A catalytic amount of an iron salt and bipyridine ligand in the presence of an organozinc base activates the ortho C-H bond of a carboxamide, and the following reaction with an alkene such as ethylene gas (1 atm), styrene derivatives, and vinylsilane or vinylboron derivatives via carbometalation gives a putative alkylzinc intermediate. This intermediate can be further reacted with electrophiles such as deuterium oxide or allyl bromide. When monosubstituted alkenes are used as a substrate, the linear alkyl product is selectively obtained. The monoalkylated product is exclusively obtained, and dialkylation does not proceed.

Amination of Phosphorodiamidate-Substituted Pyridines and Related N-Heterocycles with Magnesium Amides

The amination of various phosphorodiamidate-substituted pyridines, quinolines, and quinoxaline with magnesium amides R2NMgCl center dot LiCl proceeds at room temperature within 8 h. Several pharmaceutically active amines were suitable substrates for this amination procedure, and also the antihistaminic tripelennamine was prepared. Additionally, several heterocyclic phosphorodiamidates underwent directed ortho-metalation (DoM) using TMPMgCl center dot LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) or TMP2Mg center dot 2LiCl, followed by electrophilic functionalization prior to the amination step, which led to ortho-functionalized aminated N-heterocycles.

Theoretical Insights into Vinyl Derivatives Adsorption on a Cu(100) Surface

Here, we present a thorough theoretical study of the adsorption of acrolein (ACO), acrylonitrile (ACN), and acrylamide (ACA) on Cu(100) surface. For this purpose, we have used the density functional theory, imposing periodic boundary conditions to have a correct description of the electronic band structure of the metal and including dispersion forces through two different schemes: the D2 method of Grimme and the vdW-DF. We have found several adsorption geometries. In all of them, the vinyl group together with the amide (in ACA), ciano (in ACN), and carbonyl (in ACO) groups, is highly involved. The highest adsorption energy is found for acrylamide, followed by acrolein and the lowest for acrylonitrile (depending on the level of theory employed 1.0, and 0.9 eV, respectively). We show that a strong coupling between the pi electronic system (both occupied and virtual orbitals) and the electronic levels of the metal is mainly responsible of the chemisorption. As a consequence, electronic density is transferred from the surface to the molecule, whose carbon atoms acquire a partial sp(3) hybridization. Lone-pair orbitals of the cyano, amide, and carbonyl groups also play a role in the interaction. The simulations and following analysis allow to disentangle the nature of the interaction, which can be explained on the basis of a simple chemical picture: donation from the occupied lone pair and pi orbitals of the molecule to the surface and backdonation from the surface to the pi* orbital of the molecule (pi-backbonding).

Enantiomeric resolution of ephedrine racemic mixture using molecularly imprinted carboxylic acid functionalized resin

In the current work, we prepared an enantio-selective imprinted resin adsorbent ((+)-EMIP) with remarkable affinity for (+)-ephedrine ((+)-Eph) enantiomer. The phenolic amide derived from 4-hydroxybenzoic acid (HBA) and (+)-Eph ((+)-Eph-HBA) was first synthesized via N,N’-diisopropylcarbodiimide (DIC) activation and then copolymerized with resorcinol and formalin. The template (+)-Eph was then expelled from the resin by alkaline degradation of the amide linkage and the finally obtained (+)-EMIP resin particles exhibited a considerable selectivity toward the (+)-Eph with a capacity reached 220 +/- 1 mg/g. Also, the selectivity studies indicated a higher affinity toward the imprinted (+)-Eph enantiomer as a result of the formation of configuration-matching receptor sites that were able to fit the targeted enantiomer better than its mirror-image. Moreover, the prepared resin was successfully employed in the chiral resolution of (+/-)-Eph racemate using batch technique with (+)-Eph 87.1% enantiomeric excess in the loading supernatant solution and (-)-Eph 44.6% excess in the recovery eluant solution.

Structure-Activity Relationships of New Natural Product-Based Diaryloxazoles with Selective Activity against Androgen Receptor-Positive Breast Cancer Cells

Targeted therapies for ER+/PR+ and HER2-amplified breast cancers have improved patient survival, but there are no therapies for triple negative breast cancers (TNBC) that lack expression of estrogen and progesterone receptors (ER/PR), or amplification or overexpression of HER2. Gene expression profiling of TNBC has identified molecular subtypes and representative cell lines. An extract of the Texas native plant Amyris texana was found to have selective activity against MDA-MB-453 cells, a model of the luminal androgen receptor (LAR) subtype of TNBC. Bioassay-guided fractionation identified two oxazole natural products with selective activity against this cell line. Conducted analog synthesis and structure activity relationship studies provided analogs with more potent and selective activity against two LAR. subtype cell line models, culminating in the discovery of compound 30 (CIDD-0067106). Lead compounds discovered have potent and selective antiproliferative activities, and mechanisms of action studies show they inhibit the activity of the mTORC1 pathway.

Continuous-flow microwave-assisted extraction coupled with online single drop microextraction prior to GC-MS for determination of amide herbicides in rice samples

A rapid method based on continuous-flow microwave-assisted extraction and online single drop microextraction was first developed and applied to the determination of amide herbicides in rice. The present method has the advantages of both continuous-flow microwave-assisted extraction and online single drop microextraction, which combines extraction, separation, preconcentration, and sample introduction in one step. By continuous-flow microwave-assisted extraction, analytes were first extracted from the rice samples using 15% methanol-water, and then concentrated into single drop. The microdrop was retracted into microsyringe and directly analyzed by gas chromatography with mass spectrometry without any filtration or clean-up process. The method greatly simplifies the sample treatment procedure, reduces consumption of toxic organic solvent, and extends the application of single drop microextraction to complex solid samples. Several parameters were optimized by Box-Behnken design. Under optimal experimental conditions, good linearity was observed in the range of 2.0-500.0 mu g/kg. The limits of detection and quantification were in the range of 0.3-1.5 and 1.1-5.1 mu g/kg, respectively. The intra- and inter-day precisions were between 1.9 and 4.8%. The present method was used to the analysis of real rice samples, and the recoveries of analytes were between 80.3 and 102.3% with the relative standard deviations ranging from 1.1 to 6.9%.
