Syntheses, Crystal Structures, and Antibacterial Activity of Mononuclear Vanadium(V) Complexes with Aroylhydrazone and Pyrone as Mixed Ligands

Abstract: Two mononuclear vanadium(V) complexes, [VOL1(KA)] (I) and [VOL2(EM)] (II), where L1 and?L2 are the dianionic form of N’-(3-ethoxy-2-hydroxybenzylidene)-4-methoxybenzohydrazide (H2L1) and 4-bromo-N’-(3-ethoxy-2-hydroxybenzylidene)benzohydrazide (H2L2), respectively; KA and EM are the monoanionic form of kojic acid and ethyl maltol, respectively, were prepared. The complexes were characterized by elemental analysis, IR and UV-Vis spectra, and single crystal X-ray determination (CIF files CCDC nos. 1823339 (I) and 1823341 (II)). The crystal of complex I crystallizes in the triclinic space group P?1 with unit cell a = 7.7813(16), b = 11.297(2), c = 14.3390(18) A, alpha = 90.449(2), beta = 100.402(2), gamma = 108.366(2), V = 1173.8(4) A3, Z = 2. The crystal of complex II crystallizes in the monoclinic space group P21/n with unit cell a = 8.6935(5), b = 30.9695(18), c = 18.4469(11) A, beta = 99.366(2), V = 4900.3(5) A3, Z?= 8. The V atoms in the complexes are in octahedral geometry. The antimicrobial activities of the compounds against K. pneumoniae, S. aureus, P. aeroginosa, E. coli, and B. subtilis were investigated.

Enantiopure azetidine-2-carboxamides as organocatalysts for direct asymmetric aldol reactions in aqueous and organic media

A family of enantiopure azetidine-2-caboxamides was asymmetrically synthesized, and was examined as organocatalyst in direct aldol reactions. A well chosen chiral azetidine-2-caboxamide was found to smoothly catalyze the direct aldol reaction of various benzaldehydes with acetone in brine, and beta-hydroxy ketones were produced with enantiomeric excess up to 96%. The reaction of benzaldehydes with cyclic ketones also led to the formation of anti-products in diastereomeric ratio up to 99:1 and enantiomeric excess up to 99%.

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.Reference of 23364-44-5, you can also check out more blogs about23364-44-5

Enantioselective syntheses of beta-amino alcohols catalyzed by recyclable chiral Fe(III) metal complex

An efficient asymmetric desymmetrization of meso-epoxides with anilines catalysed by a series of simple and environmentally benign in situ generated Fe(iii) complexes based on chiral tridentate ligands L1-L7 with achiral and chiral linkers (methylene, piperazine, R/S BINOL and diethyl tartrate) was carried out at rt. The in situ generated iron metal complex based on ligand L5a emerged as improved (low catalyst loading) catalyst for asymmetric desymmetrization of meso-epoxides with anilines giving high enantioselectivity (up to 99%) and high yield (95%) of enantiopure beta-amino alcohols in 14 h. While excellent results for ARO of cyclic as well as aliphatic epoxides with anilines was achieved with in situ generated complex from the ligand L4h and Fe(iii) chloride, the catalyst was recoverable and recyclable (five times) with retention of its performance.

TRANSFORMATIONS OF MESO-LACTIDE

B/N Lewis pairs have been discovered to catalyze rapid epimerization of meso-lactide (LA) or LA diastereomers quantitatively into rac-LA. The obtained rac-LA can be kinetically polymerized into poly(L-lactide) and optically resolved D-LA, with a high stereoselectivity factor kL/kD of 53 and an ee value of 91% at 50.6% monomer conversion, by a bifunctional chiral catalyst. The epimerization and enantioselective polymerization can be coupled into a one-pot process for transforming meso-LA directly into poly(L-lactide) and D-LA.

Cu-O stretching frequency correlation with phenanthroline pKa values in mixed copper complexes

A study of Cu-O vibration frequencies in 32 isostructural mixed copper complexes containing eight differently substituted phenanthrolines and four different oxygen donor bidentate ligands, is presented. In all cases linear correlation was found between phenanthroline pKa values and the studied vibration frequencies, suggesting that an increase in phenanthroline basicity weakens Cu-O bonds in this type of compound.

Synthesis of TRIP and analysis of phosphate salt impurities

The chiral phosphoric acid TRIP, a useful Brnsted acid catalyst, easily becomes contaminated with metal impurities in the form of phosphate salts during synthesis. This significantly reduces the content of free acid in the product which can hamper the catalytic activity. Methods to easily judge whether TRIP contains mainly the free acid or phosphate salts are presented, using 1H NMR spectroscopy or a simple pH test. An improved synthetic protocol for TRIP was established that reliably produces the free acid.
