Abstract

The electrophilic displacements of the reactive anion of tetracyclic lactam 3 were investigated. Facile syntheses of 1- acetylaspidoalbidine (5) and deoxyaspidodispermine (6) were achieved by the partial reduction of a lactam carbonyl, followed by the stereoselective transannular cyclization.
