Abstract

Head-to-head photo[2+2]cycloaddition of 1,ω-di[3-(1-methyl- 2-phenylsulfanyl-1H-imidazol-5-yl)propenoyloxy]alkylenes smoothly proceeded under irradiation of a high-pressure mercury lamp to give cyclobutane compounds regio- and stereoselectively. The stereochemistry of these cyclobutanes was determined as β-form.
