Cyclohexylsulfinyl-3-methyl-1,3-butadienes 5, 6, and 1-[1- (cyclohexylsulfinyl)ethenyl]cyclohexene (7), easily prepared from cyclohexanethiol (1) via transient cyclohexanesulfenic acid (4), were reacted with N-phenylmaleimide under different conditions, at normal and high pressure. The stereochemical outcome of these cycloadditions contributes a better understanding of the relationships among different factors controlling facial diastereoselection.
