Synthesis and Antimicrobial Activity of Novel Thiazolidinone and Azetidinone Derivatives

Abstract

Reaction of 2,3-diketoquinoxaline in presence of phosphorus pentachloride and hydrazine hydrate gives 2-hydrazino-3-hydroxyquinoxalin (4) which on treatment with various aldehydes in appropriate solvent gives 2-p-anisyl-3-(3-hydroxy quinoxalin-2 yl-amino)-4-thiazolidinones (6) and 1-N-(3-hydroxy quinoxalin-2'yl-amino)-4-aryl-3-chloro-2-azetidinones (7). The structure of compounds 6a-6l and 7a-7l has been confirmed by IR and ¹H NMR data. All these compounds were tested for their antimicrobial and antifungal activity against different microorganisms.
