Application
Thiophenol can undergo: Asymmetric Michael addition to diisopropyl maleate in the presence of a catalytic amount of cinchonine to form (s)-(−)-diisopropyl phenylthiosuccinate, which can be further converted to (R)-(+)-3,4-epoxy-1-butanol. Regioselective and stereoselective 1,4-addition to alkenylidenecyclopropanes leading to endo- or cis-vinyl sulfide adducts, a key step in the synthesis of karahanaenone.Diastereoselective addition to (S)-N-(α,β-unsaturated carbonyl)-γ-[(trityloxy)methyl]-γ-butyrolactams to form the corresponding β-(phenylthio)carboxylates.
