Asymmetric Synthesis of gem-Dimethylcyclopropane-fused Compounds through Chemo-, Regio-, and Stereoselective Cyclopropanation and Stereospecific Rearrangement

Optically active gem-dimethylcyclopropane-fused compound was synthesized by a tandem reaction consisting of chemo-, regio-, and stereoselective cyclopropanation of a 4-substituted 7,7-dimethylcycloheptatriene with an internal diazo ester and following stereospecific rearrangement.
