Steroid Studies. XXVII. A New Aromatization Reaction of the Homoannular Diene System. (1). On the Structure of the Phenolic Compound derived from 3β-Acetoxylanosta-5, 8-dien-7-one.

Abstract

It was observed that the methyl group in the 19-position of 3β-acetoxylanosta-5, 8-dien-7-one (I) would be easily eliminated as methane and the B-ring was aromatized by treatment with zinc. The other chemical and photochemical behaviors of (I) were examined.
