A highly-efficient catalytic system for hydrodebenzylation reaction is described. The cleavage of O-benzyl and N-benzyl protecting groups was performed using an uncommonly low palladium loading (0.02-0.3 mol%; TON up to 5000) in a relatively short reaction time. The approach was used for a variety of substrates including pharmaceutically important precursors, and gram-scale deprotection reaction was shown. Transfer conditions together with easy-to-make Pd/C catalyst are the key features of this debenzylation scheme.

A nickel-catalyzed reductive coupling of aryl triflates with thiocarbonates is reported here. Both electron-rich and -deficient aryl C(sp(2))-O electrophiles as well as a class of O-tBu S-alkyl thiocarbonates are compatible with the optimized reaction conditions, as evidenced by 49 examples. The reaction also proceeds with good chemoselective cleavage of the C-O bond with regard to thioesters. This work broadens the scope of nickel-catalyzed reductive cross-electrophile coupling reactions.

Indole chalcones were designed and synthesized as a promising set of compounds against H(37)Rv strain of Mycobacterium tuberculosis. Within this library of compounds, (E)-1-(furan-3-yl)-3-(1H-indol-3-yl)prop-2-en-1-one (18), (E)-3-(1H-indol-3-yl)-1-(thiophen-2-yl)prop-2-en-1-one (20) and (E)-2-((1H-indol-2-yl)methylene)cyclopentan-1-one (24) displayed high anti-tubercular activity at 50 mu g/ml with MIC values of 210, 197 and 236 mu M respectively. The in-silico studies revealed that compound 18 exhibit binding modes similar to FAS-II inhibitors like INH or Thiolactomycin against KasA protein. Cytotoxicity assay results suggest that the compounds 18, 20 and 24 are non-cytotoxic to human megakaryocytes and murine B cells. (C) 2020 Elsevier Masson SAS. All rights reserved.

(E)-4-Amino-N’-(substituted benzylidene) benzohydrazides (1-8) were synthesized by condensing 4-aminobenzohydrazide with an appropriate aldehyde in the molar ratio of 1:1 in methanol as solvent. Single crystal X-ray diffraction has been recorded for compound 1. For all the synthesized compounds, FT-IR, H-1 and C-13 NMR spectra have been recorded. Also antibacterial and docking studies have been done for all compounds 1-8. Since for compound 1 only single crystal X-ray analysis has been carried out, its structural characterization have been done in detail, characterisation of remaining compounds 2-8 have been carried out by comparing their FT-IR, H-1 and C-13 NMR spectral data with that of compound 1. Single crystal X-ray analysis of 1 show that the compound exists in E-configuration about azomethine double bond. The crystal state of the compound was stabilised by the hydrogen bond present in the molecule. DFT calculations using the B3LYP/6-311++G method have been carried out for 1 to get the optimized geometry, IR and NMR frequencies, Mulliken charge distribution, molecular electrostatic potential (MEP) and energies of HOMO – LUMO. A good agreement between the DFT predicted and the experimentally measured IR and NMR spectra of 1 was found. Analysis of MEP and Mulliken atomic charges bar diagram of 1, confirms the chemical reactivity and existence of intermolecular hydrogen bonding of the molecule. The result of antibacterial and antifungal activities shows that the compounds 2, 4, 7 and 8 showed good antibacterial activity against the tested bacteria and the compounds 1, 3, 5 and 6 showed good antifungal activities against all the three fungal strains. These results showed that electron donating and electron withdrawing groups play important roles in antibacterial and antifungal activities of the compounds1-8, respectively. Molecular docking studies of compounds 1-8 shows that the various ligand of compounds 1-8 shows glide score values lies between -5.923 to -7.298, among these the compounds 6 and 8 showed excellent glide score values.

Precise catalytic regulation of carbon radical generation by a highly active oxygen radical to abstract the H atom in a C-H bond is an effective method for the selective activation of C-H synthetic chemistry. Herein, we report a facile catalyst system with commercially available copper(II)/{PMo12} to form a tert-butanol radical intermediate for the selective oxidation of benzylic C-H bonds. The reaction shows a broad range of substrates (benzyl methylene, benzyl alcohols) with good functional group tolerance and chemical selectivity. The corresponding carbonyl compounds were synthesized with good yields under mild conditions. DFT calculations and experimental analysis further demonstrated a reasonable carbon radical mechanism for this type of organic transformation reaction.

The first defluorinative ipso-functionalization reaction of (trifluoromethyl)alkenes is reported. This exclusively regioselective ipso-defluorooxylation of (trifluoromethyl)alkenes with oximes affords various attractive O-(1,1-difluoroallyl)oxime ethers efficiently via a chemoselective single C(sp(3))-F bond activation in the CF3 group. Primary mechanism studies indicated an anionic S(N)2-type substitution pathway might be involved in this transformation.

An approach for the calculation of the vaporization enthalpies of aromatic and heteroaromatic compounds at T = 298.15 K with accuracy competitive with experiment was proposed. The vaporization enthalpies may be calculated from the solution enthalpies of liquid and solvation enthalpies in benzene. The solution enthalpies of liquids were shown to be constant within a given type of aromatic compounds. For a set of 67 liquid and 41 solid aromatic and heteroaromatic compounds not capable of intermolecular hydrogen bonding, it was experimentally demonstrated that the solution enthalpies of liquids or supercooled liquids in benzene were equal to 1 +/- 1 kJ . mol(-1). The way to consider intermolecular hydrogen bonding, e.g., in phenol, aniline, pyrrole derivatives, was also proposed. The methods for solvation enthalpy calculation were proposed previously. The calculated and literature vaporization enthalpies values of 415 aromatic and heteroaromatic compounds were compared. Average absolute deviation amounted to 1.3 kJ . mol(-1). The proposed approach is especially valuable for calculation of the vaporization enthalpies of low-volatile compounds, including those solid at T = 298.15 K. (C) 2020 Elsevier B.V.

Background Bisphenol A is an important organic chemical as an intermediate, final and inert ingredient in manufacturing of many important products like polycarbonate plastics, epoxy resins, flame retardants, food-drink packaging coating, and other. BPA is an endocrine disruptor compound that mimics the function of estrogen causing damage to reproductive organs. Bacterial degradation has been consider as a cost effective and eco-friendly method for BPA degradation compared with physical and chemical methods. This study aimed to isolate and identify bacterial strain capable to degrade and tolerate high concentrations of this pollutant, studying the factors affecting the degradation process and study the degradation mechanism of this strain. Results YC-AE1 is a Gram negative bacterial strain isolated from soil and identified as Pseudomonas putida by 16S rRNA gene sequence and BIOLOG identification system. This strain found to have a high capacity to degrade the endocrine disruptor Bisphenol A (BPA). Response surface methodology using central composite design was used to statistically optimize the environmental factors during BPA degradation and the results obtained by significant model were 7.2, 30 degrees C and 2.5% for optimum initial pH, temperature and inoculum size, respectively. Prolonged incubation period with low NaCl concentration improve the biodegradation of BPA. Analysis of variance (ANOVA) showed high coefficient of determination, R-2 and Adj-R-2 which were 0.9979 and 0.9935, respectively. Substrate analysis found that, strain YC-AE1 could degrade a wide variety of bisphenol A-related pollutants such as bisphenol B, bisphenol F, bisphenol S, Dibutyl phthalate, Diethylhexyl phthalate and Diethyl phthalate in varying proportion. Pseudomonas putida YC-AE1 showed high ability to degrade a wide range of BPA concentrations (0.5-1000 mg l(- 1)) with completely degradation for 500 mg l(- 1) within 72 h. Metabolic intermediates detected in this study by HPLC-MS were identified as 4,4-dihydroxy-alpha-methylstilbene, p-hydroxybenzaldeyde, p-hydroxyacetophenone, 4-hydroxyphenylacetate, 4-hydroxyphenacyl alcohol, 2,2-bis(4-hydroxyphenyl)-1-propanol, 1,2-bis(4-hydroxyphenyl)-2-propanol and 2,2-bis(4-hydroxyphenyl) propanoate. Conclusions This study reports Pseudomonas putida YC-AE1 as BPA biodegrader with high performance in degradation and tolerance to high BPA concentration. It exhibited strong degradation capacity and prominent adaptability towards a wide range of environmental conditions. Moreover, it degrades BPA in a short time via two different degradation pathways.
