General description

Thiophenol is an organosulfur compound used as an intermediate to produce polymers.

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.
