Synthesis of 18α-fernane derivatives. A Backbone rearrangement of pentacyclic triterpenes

Abstract

Acid-catalysed deacetylation and rearrangement of an 11-oxo-γ-onocerin derivative are accompanied by inversion of the configuration at C-18, giving a conjugated ketone, the structure of which is proved by converting it into hopene-II.
