Asymmetric Copper‐Catalyzed Carbomagnesiation of Cyclopropenes

Abstract

Abstract The highly diastereo‐ and enantioselective formation of polysubstituted cyclopropanes was easily achieved through the asymmetric copper‐catalyzed carbomagnesiation reaction of nonfunctionalized cyclopropene derivatives. The carbometalated species generated in situ readily undergo C−C and C−X bond‐forming reactions with various electrophiles with complete retention of configuration.
