Abstract

Sidestepping stereochemical inversion: In an expedient, asymmetric total synthesis of (-)-frondosin B a novel palladium-catalyzed cyclization establishes the tetracyclic skeleton (see scheme). The absolute stereochemistry of naturally occurring marine metabolite (+)-frondosin B, an interleukin-8 inhibitor, has been reassigned. Tf = trifluoromethanesulfonyl.
