An efficient strategy for the synthesis of various 1,4,5,6- tetrahydropyrimidine and 2-imidazoline derivatives has been reported. The reactions proceeded from nitriles with ethylenediamine or 1,3-diaminopropane via cascade cycloaddition in the presence of CuL2 (L = 2-hydroxy-2-phenylacetate) to afford the corresponding 1,4,5,6- tetrahydropyrimidine or 2-imidazoline derivatives under reflux conditions or microwave irradiation in excellent yields.
