Oxidative conversion of δ-sultones to γ-lactones.

Duminda S Liyanage1, Christian S Jungong1, Alexei V Novikov1.   

Abstract

Delta-sultones, prepared by C-H insertion, can be oxidatively converted to gamma-lactones by treatment with t-BuOK/t-BuOOH. An intermediate in the synthesis of (-)-eburnamonin was prepared using this approach.
