A transformation of cyclopropyl carbenegenerated from 2-cyclopropyl-2-diazoacetate via oxonium ylide was found by trapping the resulting ylide with imine. The asymmetric three-component reaction of cycloproyl diazoacetates, benzenemethanols and imines afforded a rapid and efficient method to synthesize complex cyclopropane derivatives with excellent diastereoselectivity and enantioselectivity.
