reduction–aza-Wittig sequence. The latter serves as a universal precursor to the targets. Key carbon–carbon bond constructions include highly diastereoselective acetylide additions to the N-methyliminium ion derived from 39 and Friedel–Crafts and Hosomi–Sakurai cyclizations to construct the carbocyclic skeleton of the targets. Initially, this strategy was applied to the syntheses of (−)-acutumine (4), (−)-dechloroacutumine
