Two different cyclohexylsulfinyl-3-methyl-1,3-butadienes and 1-[1-(cyclohexylsulfinyl)ethenyl]cyclohexene , easily prepared from a cyclohexanethiol via transient cyclohexanesulfenic acid , 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.

Abstract
Two different cyclohexylsulfinyl-3-methyl-1,3-butadienes and 1-[1-(cyclohexylsulfinyl)ethenyl]cyclohexene , easily prepared from a cyclohexanethiol via transient cyclohexanesulfenic acid , 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.File in questo prodotto:
