Toward a unified approach for the lycopodines: synthesis of 10-hydroxylycopodine, deacetylpaniculine, and paniculine.

ABSTRACT: The enantioselective syntheses of 10-hydroxylycopodine, deacetylpaniculine, and paniculine have been accomplished through use of a common intermediate. Key steps in the synthetic sequence toward these lycopodium alkaloids include formation of the tricyclic core via a conformationally accelerated, intramolecular Mannich cyclization and an organocatalyzed, intramolecular Michael addition to form the C(7)-C(12) linkage.
