- Department of Chemistry, Maharshi Dayanaud University, Rohtak-121 001 Manuscript received 28 March 1988, accepted 2 November 1988 2-Amino-5-alkylthiadiazoles (1) condense with \(\propto\)-haloketones and 2,3-dichioroquinoxalene to furnish respectively the cyclised products, 2,6-disubstituted imidazo [2,1-b]-1,3,4-thiadiezoles (2) and 2-substituted-thiadiazolo[2ʹ,3′ : 2,1]imidazo[4,5-b1- quinoxaline (4). Bromination of 2 furnishes 5-bromo-2,6-disubstituted-imidazo[2,1-b]- thiadiszoles (3). The antimicrobial activities of some of the compounds have been evaluated.
