Application

  • (S)-(−)-Propylene oxide undergoes ring-opening upon treating with nucleophiles such as Grignard reagents or organolithium compounds to yield corresponding secondary alcohols.[1][2]
  • It can be used in the synthesis of ligands to prepare of Pb(II) based coordination nets for the fabrication of white light-emitting diode materials.[1]
  • It is a key starting material for the total synthesis of arenolide[2] and (+)-aspicilin.[3]
