of the lowest oxidized members of the eudesmane family of natural products, is presented. The final synthetic sequence illustrates a nine-step, gram-scale, enantioselective route to this bicyclic terpene with excellent stereocontrol and in 21% overall yield.

logic needed for the cyclase phase of terpenesynthesis, particularly in the area of polyene cyclizations, much remains to be learned if the oxidase phase is to be mimicked in the laboratory. Here we show how the logic of terpene biosynthesis has inspired the highly efficient and stereocontrolled syntheses of five oxidized members of the eudesmane family of terpenes in a modicum of steps by a series of
