A Short and Efficient Asymmetric Synthesis of (±)-epi-Cytoxazone from cis-(1R,2S,5R)-Menthyl 4-Methoxyphenylglycidates

  • Mustafa Er
  • Necdet Coskun

The racemic epi-cytoxazone was synthesized, starting from p-anisaldehyde, in five steps and 48% overall yield. An efficient synthesis of azido alcohols has been achieved by regioselective ring opening of glycidates using NaN3 in MeOH–H2O. The key step of the process is reductive cyclization of azide carbonates by Zn–TMSCl.
