Synthesis of some Novel Metal Complexes of 4-Hydroxy Benzopyran-2-Ones as Antimicrobial Agent
Complexes of 3-[{3-(3'-bromo phenyl)}-prop-2-enoyl]-4-hydroxy-6-methyl-2H-chromen-2-one with Cu(II), Ni(II), Fe(II), Co(II) and Mn(II) have been synthesized and characterized using elemental analysis, IR spectra and conductivity measurements. These studies revealed that they are having octahedral geometry of the type [ML2 (H2O)2]. In-vitro antimicrobial activity of all synthesized compounds and...
متن کاملSYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...

متن کاملSynthesis and structural determination of novel 5-arylidene-3-N(2-alkyloxyaryl)-2-thioxothiazolidin-4-ones.
As part of our project devoted to the synthesis of heterocycles including thiazole rings, some new 5-arylidene-2-thioxo-3-N-arylthiazolidin-4-ones were synthesized by Knoevenagel condensation. An interesting feature of these compounds is that their chirality is induced by that of their 3-N-(2-alkyloxyaryl)-2-thioxothiazolidin-4-one precursors, which in turn is due to the presence of a C2 axis o...
متن کاملSynthesis and Antimicrobial Evaluation of New (4-Oxo-thiazolidinyl)quinazolin-4(3H)ones of 2-[(2,6-Dichlorophenyl)amino]phenylacetic acid
Synthesis of 2-[2-(2,6-dichlorophenyl)amino]phenylmethyl-3-[4-(2-substitutedphenyl-4-oxo-thiazolidinyl)aryl]-6-bromo quinazolin-4(3H)ones VIa-j have been achieved from the starting material 2-[(2,6-dichlorophenyl)amino] phenylacetic acid I to benzoxazine III, Further reaction with p-phenylindiamine and substituted aromatic aldehyde gave 2-[2-(2,6-dichlorophenyl)amino]phenyl methyl-3-(4-aminoary...
