[reaction: see text] A general approach to the tricyclic core of the icetexane naturalproducts via the cycloisomerization of alkynyl indenes using GaCl(3) is presented. This strategy provides an efficient synthesis of the naturalproduct salviasperanol and sets the stage for access to other members of this family of diterpenoids.
