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 lycopodiumalkaloids include formation of the tricyclic core via a conformationally accelerated, intramolecular Mannich cyclization and an organocatalyzed, intramolecular Michael addition to form the
10-羟基番茄碱、脱乙酰稻番碱和稗番碱的对映选择性合成已通过使用常见的中间体完成。这些石松生物碱合成序列的关键步骤包括通过构象加速的分子内曼尼希环化和有机催化的分子内迈克尔加成形成三环核心以形成 C 7 –C 12键。
