Abstract
A Facile route to some new thiophene derivatives via the reaction of 3-mercapto-2-(1-methylbenzimidazole-2-carbonyl)-3-phenylaminopropenal (3) with 1-aryl-2-bromoethanones, chloroacetonitrile and ethyl bromoacetate is reported. Reaction of 3 with hydrazonoyl halides afforded 1,3,4-thiadiazole derivatives incorporating a benzimidazole moiety. Antimicrobial and antifungal activities of selected examples of the new products were evaluated.
