    Abstract: Phosphine-assisted annulation of thiophene-2,3-dicarbaldehyde with N-substituted maleimides provided the N-substituted benzo[b]thiophene-5,6-dicarboximides in good to high yields. Introduction of cyano and aryl groups to the thiophene moiety of the N-cyclohexyl product was achieved by metal-catalyzed coupling reactions via its bromo derivative. Pho... Show More
