Synthesis of (-)-laulimalide: an agent for microtubule stabilization

An enantioselective synthesis or (-)-laulimalide is described. Key reactions include a convergent allylation coupling reaction, asymmetric conjugate addition, the allenylstannane Ferrier reaction and a chelation-controlled alkenylzine addition as the basis for stereocontrol in critical elements of chirality.
