Abstract: A series of 3-(2-substituted sulfanyl-imidazo [2,1-b][1,3,4] thiadiazol-6-yl)-chromen-2-ones (3) have been synthesized from 3-(2-bromo acetyl) chromen-2-ones 1 and 2-amino-5-thio substituted[1,3,4]thiadiazole 2 in anhydrous ethanol. The 7,8-benzo analogs of 3-(2-substituted sulfanyl-imidazo[2,1-b][1,3,4] thiadiazol-6-yl)-chromen-2-ones 5 have been synthesized under similar conditions. All the synthesized compounds have been characteriszed by analytical and spectral data.
