Total synthesis of spinosyn A. 1. Enantioselective construction of a key tricyclic intermediate by a multiple configurational inversion scheme

The condensation of (+)-7,7-dimethoxynorbomen-2-one with the cerium reagent derived from enantiopure bromide (+)-11 gives rise to an exo carbinol, which readily undergoes highly stereocontrolled anionic oxy-Cope rearrangement. Conversion of the resulting
