A highly efficient strategy for the synthesis of functionalised carbocyclic enaminonitriles in excellent yields has been described. The reaction utilises Yb(OTf)3 catalysed CâC bond cleavage and two simultaneous CâC bond formations of donorâacceptor (DA)-cyclopropanes with malononitrile anions in a domino fashion.
