摘要

Cycloaddition reactions between 2-vinylthiophen and the dienophiles maleic anhydride, dimethyl acetylenedicarboxylate,'methyl propiolate, and methyl acrylate, are reported. Products include simple benzo [b] thiophen 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).
