Abstract
Treatment of a 17-hydroxyimino-steroid with refluxing acetic anhydride and pyridine affords an equilibrium mixture of 13-epi-enimide and 13-epi-enamide. A free-radical mechanism is proposed. Acidic hydrolysis gives the 17-oxo-13-epi-steroid in high overall yield.This publication has 1 reference indexed in Scilit:
