Abstract
The syntheses of 3-substituted-, 2,3-disubstituted-5,6-dihydro-4H-imidazo[2,1-b]thiazoles and 3-substituted-, 2,3-disubstituted-4,5,6,7-tetrahydrothiazolo[3,2-a]pyrimidines have been achieved by reacting ketones with 2-mercaptoimidazoline and 2-mercapto-3,4,5,6-tetrahydropyrimidine respectively in the presence of iodine. The condensation has also been affected by replacing iodine with bromine.Keywords
