Enantioselective total synthesis of lycopodine
The first enantioselective total synthesis of lycopodine has been completed. Key steps include a highly diastereoselective organocatalyzed cyclization of a keto sulfone to establish the key C-7 and C-8 stereocenters and a tandem 1,3-sulfonyl shift/intramolecular Mannich cyclization to form the tricyclic core.
