Rearrangements of the C/D ring system of the tetracyclic diterpenoid, aphidicolin
Abstract
The generation of a C-16 carbocation in the aphidicolane series by the hydrolysis of a 15β,16β- or a 16β,17-epoxide is shown to lead, inter alia, to skeletal rearrangement products arising from the migration of the C(12)–C(13) bond to C-16.
