Journal of the Chemical Society D: Chemical Communications Pub Date: DOI: 10.1039/C29700001488

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.
