You, Lin Liang, Xin-Ting Xu, Ling-Min Wang, Yue-Fan Zhang, Jia-Jun Su, Qi Li, Yuan-He Zhang, Bo Yang, Shou-Liang Chen, Jia-Hua Yang, Zhen Asymmetric Total Synthesis of Propindilactone G A concise total synthesis of (+)-propin­di­lactone G, a nor­tri­terpenoid isolated from the stems of <i>Schisandra propinqua</i> var. <i>propinqua</i>, has been achieved for the first time. The key steps of the synthesis include an asymmetric Diels–Alder reaction, a Pauson–Khand reaction, a Pd-catalyzed reductive hydrogen­olysis reaction, and an oxidative hetero­coupling reaction. These reactions enabled the synthesis of (+)-propin­di­lactone G in only 20 steps. As a consequence of our synthetic studies, the structure of (+)-propin­di­lactone G has been revised. 20 steps;Schisandra propinqua var;synthesis;Propindilactone GA 2015-08-19
