A short, new route to the title tetracyclic substructure of Sf/cycho4 alkaloids, consisting in the nucleophilic attack of an ester a-anion to a pyridinium salt, acid-induced cyclization of the resultant 1,4\_dihydropyridine, and stereospecific elaboration of the ethylidene substituent, is reported.
