wuweizisu C (4), gomisin J (6), gomisin N (7), and γ-schizandrin (8) having natural configuration were accomplished in a stereoselective manner. The catalytic hydrogenation or the metal mediated 1,4-reduction of the tetracyclic lactones (12, 17, 22, 30) played the significant role for the stereoselective introduction of C6, C7 dimethyl moiety. Furthermore, the neighboring carbonyl group assisted regioselective
具有立体构型的无味子素C(4),gomisin J(6),gomisin N(7)和γ-五味子素(8)的总合成以立体选择性方式完成。催化氢化或金属介导的1,4-还原四环内酯的(12,17,22,30)所起的作用显著为立体选择性引入C6,C7二部分组成。此外,相邻的羰基辅助5的区域选择性脱甲基对于6的合成是必不可少的。
