configurational assignment of the cytotoxic marinemacrolide phorbaside A has been verified by the stereodefined synthesis of the proposed structure 1 and its (18S,19R)-diastereomer 3, followed by correlation using circular dichroism spectroscopy. This first total synthesis, which proceeds in 8.2% yield over 23 steps, features two 1,4-syn boron aldol reactions, a Sonogashira coupling, and an α-glycosylation to append
