Abstract Dibenzalacetones 1a-c reacted with cyanothioacetamide (2) to give the new styrylpyridinethione derivatives 3a-c which were used as the starting materials for the synthesis of other several heterocyclic compounds. Reactions with chloroacetone (4). N-arylmaleimides 7a,b, and ethyl iodide gave 2-S-acetonyl pyridines 5a-c, pyrrolo[3,4-flquinolines 9a-f, and 2-S-ethylpyridines lla-c, respectively
