[reaction: see text] A general approach to the tricyclic core of the icetexane natural products via the cycloisomerization of alkynyl indenes using GaCl(3) is presented. This strategy provides an efficient synthesis of the natural product salviasperanol and sets the stage for access to other members of this family of diterpenoids.
[反应:见正文]提出了一种通过使用GaCl(3)炔基茚基的环异构化方法来制备icetexane天然产物的三环核心的一般方法。该策略提供了天然产物丹参戊醇的有效合成,并为获得该双萜类家族的其他成员奠定了基础。
