Synthesis of the 5-7-6 core of guanacastepenes. Construction of C8 quaternary carbon via the inversion of stereochemistry.

[formula: see text] An efficient and unique route to the 5-7-6 core of guanacatepene A (1) is described. The installation of the desired stereochemistry at the C8 position was achieved via the desymmetrization of the cyclohexadienone by reductive ring clo
