Diterpenes. Part X. Some transformations of phyllocladene and isophyllocladene

Abstract
The products from, and the effect of solvent on the ring-opening of 15α,16-epoxyphyllocladane (1) and of 16,17-epoxyphyllocladane (17) with boron trifluoride have been examined. The action of other Lewis acids has also been investigated. Treatment of 15α,16-epoxykaurane (21) with boron trifluoride–ether complex results in rearrangement, giving atisiran-15-one (25). Photo-oxygenation of phyllocladene (6) and isophyllocladene (19) has been studied; a minor product from the latter reaction is 15α,16-epoxyphyllocladan-17-ol (2).
