Two down more to go: The asymmetric syntheses of (-)-pentazocine and (-)-eptazocine are presented. The highlights of the syntheses are the construction of the core skeleton through an aza-Prins cyclization and intramolecular Friedel-Crafts reaction.
呈现了(-)-戊诺啡和(-)-依他佐辛的不对称合成。合成的重点是通过氮杂-Prins 环化和分子内傅克反应构建核心骨架。
