The chiral ligand " -N-salicylidene-4-amino 2.2 paracyclophane 1 was synthesized and resolved. Resolved 1 was Ž . complexed to copper II for use as an asymmetric catalyst for the cyclopropanation of selected styrenes and stilbenes by diazoesters. Conversions of styrenes to cyclopropanes were high, t
