Abstract

Abstract A series of new 2??amino??3??cyano??4??aryl??1, 4, 5, 6??tetrahydrobenzo [h] chromenes derivatives were synthesized by the reaction of malononitrile with 2??arylmethylidene??3, 4?? dihydro??1 (2 H)??naphthalenone in N, N??dimethylformamide (DMF) at 80° C catalyzed by KF?? Al2O3. The structure of the product was confirmed by x??ray analysis.
