Synthesis and in-vitro antimicrobial screening of 3-cinnamoyl coumarin and 3-[3-(1H-indol-2-yl)-3-aryl-propanoyl]-2H-chromen-2-ones
An efficient synthesis of some novel coumarin derivatives via 1, 4- Michael addition of indole to coumarin chalcones catalyzed by cellulose sulphonic acid (CSA) under solvent free conditions is described. The corresponding Michael addition products were obtained in good to excellent yield. The synthesized compounds were screened for their antibacterial activity against E. coli, S. aureus and an...

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 antifungal activities of 2-(N-arylsulfonylindol-3-yl)-3-aryl-1,3-thiazinan-4-ones.
A series of 2-(N-arylsulfonylindol-3-yl)-3-aryl-1,3-thiazinan-4-one derivatives were synthesized and evaluated in vitro against seven phytopathogenic fungi, namely Fusarium graminearum, Alternaria solani, Fusarium oxysporium f. sp. vasinfectum, Alternaria brassicae, Valsa mali, Alternaria alternata, and Pyricularia oryzae. Among all derivatives, especially compound 4j exhibited a potential anti...
