The enantiomerically pure tetracyclic ABCE subunit of manzamine A has been constructed by an intramolecular Diels-Alder reaction of the vinylogous imide 13 to give the ABC tricyclic core 14; elaboration of 14 into 16 followed by a novel olefin metathesis reaction to form the azocine ring then delivered the tetracycle 17.
