An unprecedented gold-catalyzed diastereoselective cycloisomerization of 1,6-diynes bearing an alkylidene cyclopropane moiety has been developed. This methodology enables rapid access to a variety of 1,2-trimethylenenorbornanes, which are important building blocks in the preparations of abiotic and sesquiterpene core structures.
已开发出一种前所未有的金催化的、带有亚烷基环丙烷部分的1,6-二炔的非对映选择性环异构化反应。该方法能够快速获得多种1,2-三亚甲基降冰片烷,它们是制备非生物和倍半萜核心结构的重要构建单元。
