Strictamine and rhazinoline are representative methanoquinolizidine‐containing akuammiline alkaloids that possess different stereochemistry at the C16 position. A unified approach to the enantioselective total syntheses of these two molecules is described. The key steps in this synthesis include a photocatalytic intra/intermolecular type II radical cascade reaction, a Tsuji–Trost allylation, a palladium‐ or nickel‐mediated cyclization, and a late‐stage intramolecular N‐alkylation reaction.
