Abstract
Photoirradiation of α-arylthiophene derivatives linked with an alkene moiety through a three-atom spacer gave unprecedented cyclobutene-fused perhydrothiapentalene-type compounds in high yields, but neither [2 + 2] nor [4 + 2] cycloaddition products. The reaction afforded a single diastereomer in many cases. The chemical structure and relative configuration of a typical product were unambiguously determined by X-ray crystallographic analysis.
