The metalloradical catalysts [Co(D2-Por*)] have been shown to be highly effective for asymmetric intermolecular cyclopropanation of a broad scope of substrates with differentclasses of carbene sources, particularly including acceptor/acceptor-substituted diazoreagents, with this catalyst system, we could synthesize highly functionalized cyclopropanes in excellent diastereoselectivity and enantioselectivity.
