Optimal TBHP allylic oxidation of Delta5-steroids catalyzed by dirhodium caprolactamate.

Hojae Choi1, Michael P Doyle.   

Abstract

Dirhodium caprolactamate is the most efficient catalyst for the oxidation of Delta5-steroids to 7-keto-Delta5-steroids by 70% tert-butyl hydroperoxide in water (T-HYDRO). Isolated product yields range from 38 to 87%.
