The stereoselective preparation of the tetracyclic core of the manzamine alkaloids via the intramolecular vinylogous amide photocycloaddition/retro- Mannich fragmentation/Mannich closure cascade is described. The striking effect of unsaturation in the eight-membered ring on the stereoselectivity of the cycloaddition and a computational analysis of these results are presented.
