sequence include organocatalytic, intramolecular Michael addition of a keto sulfone and a tandem 1,3-sulfonyl shift/Mannich cyclization to construct the tricyclic core ring system. Synthetic work toward this natural product family led to the development of N-(p-dodecylphenylsulfonyl)-2-pyrrolidinecarboxamide, an organocatalyst which facilitiates enantioselective, intramolecular Michael additions.

Synthesis of the core skeletons of the polycyclic alkaloids lycopodine and porantherine has been accomplished employing as a key step an Intramolecular Azide-Olefin Cycloaddition reaction (IAOC)/enamine addition/Mannich cascade reaction. Applying this methodology, the first synthesis of C15-desmethyl lycopodine has been developed.
