An alternative synthesis of (f)-vinoxine, based on the nucleophilic addition of an ester a-anion to a 3-acetylpyridinium salt, acid-induced cyclization of the resultant 1.4-dihydropyridine, and stereoselective elaboration of the @)-ethylidene substituent, is reported. Vinoxine' is a minor indole alk
