An efficient and convenient multicomponent reaction for preparation of 2-amino-4-aryl-6,7,8,9-tetrahydro-5H-benzo[7]annulene-1,3-dicarbonitrile derivatives, in THF, with DBU as catalyst is reported. These compounds are typical acceptor–donor–acceptor (A–D–A) systems comprising one electron donor and two electron acceptors with different important chemical properties. Excellent yields and the simplicity of the reaction procedure make this one of the most efficient methods for synthesis of these types of compound.
