Abstract

Summary: A novel concept for performing a one-flask cyclopropanation of conjugated enones consists of conjugate addition of an appropriate phenylthio-stabilized organolithium compound followed by treatment of the resulting enolate anion with cuprous trifluoromethanesulfonate. The cyclopropanes generated by this procedure can be simple ones, substituted for example by silyl-and
