Abstract
The arylidene derivatives (1) of 1,3-thiazolidine-2,4-dithione undergo 1,4-cycloaddition reaction with acrylonitrile, ethyl acrylate, ω-nitrostyrene, styryl ethyl ketone and N-aryl-maleimides leading to substituted tetrahydrothiopyrano-7 H[2,3-d]thiazole-2thiones (2), (8) and (4). Grignard reagents effects addition to the double bond of the lateral chain of 1 to yield products proved to have structure 7.Keywords
