Abstract

The α,β-unsaturated cyanoester was obtained from p-methoxy benzaldehyde and ethyl cyano acetate by reported method. The conjugated addition products were synthesized from alkyl or aryl bromides and α,β-unsaturated cyanoester in the presence of 10 mol % Cu(I) catalyst in high yields within 17-21 min under ultrasound irradiation.
