Synthesis of the title compound represents the first construction of any of these potent, antitumorAnnonaceousacetogenins with the entire relative stereochemistry in place. Palladium(0)-mediated crossed diyne coupling and the use of three, natural, α-hydroxy acids as the origin of all absolute stereochemistry highlight this flexible approach that sets the stage for access to structural analogs for
