Studies toward the total synthesis of dumsin. 2. A second generation approach resulting in enantioselective construction of a functionalized ABC subunit of the tetranortriterpenoid insect antifeedant

A synthesis of the ABC framework of dumsin is described. The optically active intermediate 9b, which is expeditiously assembled from 5-oxobornyl pivalate by the sequential implementation of an oxy-Cope rearrangement and an intramolecular ene reaction, pro
