Abstract

Summary: The trans-decalin lactone (ll), an advanced intermediate towards forskolin (l), has been elaborated in five steps from the bromo-acetal (4) using a novel stereoselective intramolecular radical mediated cyclisation reaction,*(4)+(5), in tandem with an intramolecular Mukaiyama aldolisation, viz (lO)+(ll).
