Direct Access to Polyannulated Azacyclics Through a Cascade Double Annulation of Allenamines Triggered by Friedel–Crafts Alkylation and Nucleophilic Substitution

Here, we report a direct synthesis of polyfused azacyclics bearing an all‐carbon quaternary center from propargyl alcohols (PAs) and 2‐pyrrolyl anilines, catalyzed by Sc(OTf) 3 under solvent‐free conditions. This approach involves the cascade double annulation of in situ‐formed a...
