Synthesis of xestobergsterol A from dehydroepiandrosterone

Xestobergsterol A, a potent inhibitor of histamine release, has been synthesized from dehydroepiandrosterone in a route that used introduction of a novel 15-oxygen functionality, side-chain construction via the orthoester Claisen rearrangement and TBAF-pr
