Both electron-rich and electron-deficient olefins - such as styrene and methyl methacrylate - undergo efficient (yields > 90%) cyclopropanation with ethyl diazoacetate as the carbene source to give predominantly trans products with exceptionally high enantioselectivity when the (salen)Ru catalyst shown is used (see scheme).
