Synthesis of the cis-decalin portion of vinigrol using a tandem oxy-Cope/Claisen/ene reaction is described. This three pericyclic reaction cascade proves to be a valuable synthetic tool in the construction of such systems.

A concise synthesis of fumagillol was accomplished in twelve steps starting from cyclohexadiene, proceeding by way of ring-opening of a symmetrical protected epoxydiol with a cuprate reagent and subsequent protecting group manipulation to give a key ketone intermediate. Installation of the required epoxide functions was achieved by addition of chloromethyllithium to the ketone and by directed epoxidation of the unsaturated side-chain.
