Cycloaddition reactions between 2-vinylthiophen and the dienophiles maleic anhydride, dimethyl acetylenedicarboxylate, methyl propiolate, and methyl acrylate, are reported.Products include simple benzotiophen carboxylates (6, 13, 17) and reduced derivatives (3, 4, 18).The acetylenic dienophiles also gave a dihydrobenzthienyl-acrylate (16) or -fumarate (11), and the dithienylcyclohexene esters (7) and (14).
