logic, a scalable and enantioselective divergent synthesis of germacrane‐type sesquiterpenes is developed. Salient features of this work include: 1) the direct ring closure of a farnesol derivative to the 10‐membered carbocycle 1, and 2) subsequent synthetic operations on 1 to gain access to different bicyclic frameworks such as guaianes, cadinanes, selinanes, and elemenes.
萜烯环化酶阶段:受此逻辑的启发,开发了一种可扩展的对映选择性发散合成锗烷型倍半萜烯。这项工作的显着特点包括:1) 法尼醇衍生物与 10 元碳环1的直接闭环,以及 2) 对1 的后续合成操作以获得不同的双环骨架,如愈创木酚、卡地烷、硒烷和榄香烯.
