of the synthesis include (a) use of a chiral auxiliary controlled asymmetric Diels-Alder reaction to provide the desired absolute and relative stereochemistry at C-4a, C-6, and C-8a, (b) an efficient alkylation of hindered iodide 13 using a novel amide benzophenone imine, (c) oxidative ring opening of the [2.2.2] bicyclic system to simultaneously functionalize the molecule for intramolecular cyclization
