Abstract:Abstract

3-Aryloxymethyl-4-phenyl-5-mercapto-s-triazoles (Ia-c) have been synthesized and reacted with N-chloroacetyl derivatives of aromatic and/or heterocyclic amines to yield 5-(N-aryl/heterocyclyl)-carboxamidomethyl thio-s-triazole derivatives 2a-o and 3a-o respectively. Reaction of Ia-u with ethyl chloroacetate gave the corresponding esters 4a-c which were reacted with hydrazine hydrate to give hydrazides 5a-c. Condensation of 5a-c with aromatic aldehydes gave Schiff s bases 6a-u with on cycloaddition reaction with thioglycolic acid yielded 4-thiazolidinones 7a-g. Some of these compounds were screened in vitro for their antibacterial activities.
Keywords:Key words:  Synthesis  thio-s-triazoles  thiazoles  mercaptoesters  hydrazines  hydrazones and thiazolidinones
