Late-Stage Transformation of Carboxylic Acids to N-Trifluoroethylimides with Trifluoromethyl Diazomethane

We report the first systematic evaluation of the reaction of trifluoromethyl diazomethane (2,2,2-trifluorodiazoethane, CF3CHN2) with drug-like molecules. We found our previous copper-catalyzed transformation of carboxylic acids to the corresponding N-trifluoroethylimides with CF3CHN2 and acetonitrile is well-suited for the latestage modification of drug and drug-like acids. A procedure that enables the use of solid nitriles and nitriles with high boiling points as viable substrates is also disclosed.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 578-95-0. SDS of cas: 578-95-0.

Development and comprehensive HS-SPME/GC-MS analysis optimization, comparison, and evaluation of different cabbage cultivars (Brassica oleracea L. var. capitata L.) volatile components

Seven parameters of the headspace solid phase micro-extraction (HS-SPME) for extracting volatile compounds from cabbage were optimized comprehensively for the first time. A total of 75 volatiles were identified and quantified in 10 cabbage cultivars, mainly including aldehydes, hydrocarbons, esters, isothiocyanates, alcohols, ethers, nitriles and thiazoles. Dimethyl ether was the most abundant volatile. There were 24 volatiles with the odour activity values (OAVs) greater than 1 making large contributions to the cabbage flavor. Pungent aroma was the strongest odour, followed by green and fruity aromas. In short, the overall OAV of purple cabbages were generally higher than that of green cabbage. The volatile profile of 10 cabbage cultivars could be distinguished on the basis of radar fingerprint chart (RFC), hierarchical cluster analysis (HCA) and principal component analysis (PCA). Therefore, this study not only developed a feasible method to distinguish different cabbage cultivars, but also established a theoretical basis for the genetic improvement of cabbage flavor.

Synthesis of Fused Six-Membered Lactams to Isoxazole and Isoxazoline by Sequential Ugi Four-Component Reaction and Intramolecular Nitrile Oxide Cyclization

The advanced organic chemistry experiments describe the preparation of fused six-membered lactams to isoxazole and isoxazoline by employing Ugi four-component reaction (U-4CR) and intramolecular nitrile oxide cyclization (INOC) synthetic sequence. The experiments were carried out in 28 h (overnight for U-4CR) and 2 h (for INOC) using commercially available starting materials. The two-step reaction involves the in situ imine formation in the one-pot multicomponent reaction and in situ nitrile oxide formation in the INOC. The experiments are useful in the organic chemistry curriculum for the introduction of a onepot multicomponent reaction and 1,3-dipolar cycloaddition reactions.

Fabrication, characterization, dielectric properties, thermal stability, flame retardancy and transport behavior of chlorinated nitrile rubber/hydroxyapatite nanocomposites

This work focused on the preparation of chlorinated nitrile rubber (Cl-NBR)/hydroxyapatite (HA) nanocomposites by an open two-roll mixing mill. The formation of nanocomposites was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The dielectric properties and flame retardancy of polymer nanocomposites were analyzed with special attention to the loading of HA nanoparticles. Diffusion and permeation properties of petroleum solvents through the prepared Cl-NBR/HA composites were also investigated in detail as a function of filler content, different temperatures and nature of solvent. The incorporation of HA in Cl-NBR has been endorsed by FTIR analysis. The XRD showed the crystalline peaks of HA in the polymer chain. SEM images revealed that the nanoparticles were uniformed distributed in the polymer network with spherically shaped particles. TGA results indicated that the thermal stability of nanocomposites was remarkably higher than the pure Cl-NBR and the thermal stability increases with the loading of nanoparticles. The dielectric study observed a decreasing dielectric constant with increasing frequency, and the maximum property was obtained for 7 phr HA filling in Cl-NBR. The flame resistance of the polymer composites was greatly enhanced by the incorporation of nanoparticles. The diffusion, sorption and permeation constants were found to decreased with increase in HA content. The solvent uptake decreases with the size of the penetrant molecules, and the mechanism of transport of Cl-NBR composite was anomalous in nature. The enthalpy and entropy changes of the nanocomposites were analyzed from the diffusion data. The composite containing 7 phr HA sample showed higher dielectric properties and better solvent resistance properties.

An EPR study of wheat seeds by the use of nitroxide spin probes

The viability of a variety of wheat seeds Mas investigated by use of the EPR technique, Three different types of spin probes (4-Hydroxy-TEMPO (TANOL), 3-Carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy, 3-Carbamoyl-PROXYL) were utilized in examining the viability of embryo cells. The penetration of the spin probe across the membrane was observed via the change in signal intensity against time for dry embryos of the variety of wheat seeds soaked in aqueous solutions of spin probe and line broadening agent. From the analysis of the signal intensity-time curves (i.e. rehydration curves) it was observed that the two kinds having different genetic roots (Bezostaya, Kunduru) exhibit similar saturation behaviour whereas Gerek saturates much more easily. The rehydration curves for naturally aged seeds indicates that aging causes rapid saturation and an important decrease in the signal intensity. In order to get better insight on the effect of the signals from polar and nonpolar regions on the experimental spectra, these spectra were simulated by the use of the theoretical models developed.

Nitrile group as IR probe to detect the structure and hydrogen-bond properties of piperidinium/pyrrolidinium based ionic liquids and acetonitrile mixtures

The use of molecular solvents has been proposed as a simple solution to reduce the high viscosities of neat ionic liquids (ILs) and extend the practical applications of ILs. A proper understanding of the structure and intermolecular interaction is of vital importance for the design, optimization and synthesis of ILs systems with tailored properties for specific applications. In this work, the structure and hydrogen-bond features of the representative pyrrolidinium/piperidinium based ILs and acetonitrile mixtures were studied by a combination of Fouriertransform infrared spectroscopy (FTIR) and density functional theory (DFT) calculations. The nu(C N) region is sensitive to the microenvironment and is used as IR probe to detect the structure and hydrogen-bond properties of the two IL-acetonitrile binary systems in the whole concentration range. Positive peaks are observed in the excess IR spectra of nu(C N) region which indicates the non-ideality of the mixing process and the formation of hydrogen-bonded complexes in the mixtures. With the help of deconvolution and DFT calculations, the species transformation in the mixing process can be identified from the excess spectra: When x(CD3CN) is less than 0.90, acetonitrile mainly interacts with the ion pairs and ion clusters of the ILs. Ion clusters are all broken out into ion pairs and the interaction complex is mainly ion pair-CD3CN when x(CD3CN) > 0.90. In the whole concentration range, the CD3CN cannot break apart the strong coulombic interactions between the cation and anion, and the individual cation and anion do not exist in the mixtures. All of the hydrogen-bonds in the ion pair/ion clusteracetonitrile complexes are weak strength, closed shells and electrostatically dominant interactions. (C) 2020 Published by Elsevier B.V.

Synthesis of Highly Substituted 3-Pyrrolin-2-ones from N,N-Disubstituted alpha-Amino Acids

Highly functionalized 5-membered N-heterocyclic compounds, 4-aryl-3-chloro-5-methoxy-1-methyl-3-pyrrolin-2-ones, have been synthesized in moderate to high yields by the reaction of N,N-dimethylated aromatic alpha-amino acids with oxalyl chloride, followed by solvolysis with MeOH. The products possess a number of functional groups such as an amide, a mixed amido/alkoxy acetal, a vinyl halide, and an alkene and thus are promising candidates to be used as starting materials for the synthesis of diverse five-membered N-heterocyclic compounds.
