Famesol peroxy ester

The regioselective intramolecular epoxidation of the peroxy ester (163), which can be prepared from famesol, has been effected by treating it with Cu(OCOCT3)2 (equation S ). This reaction provides a convenient route for the preparation of the 6,7-epoxide (164), which cannot be synthesized from farnesol by conventional methods or even by template-directed epoxidation using Mo(C(5)6/rBHP.
