3-Amino-1-aryl-9-methoxy-5,6-dihydro-1H-benzo[f]chromene-2-carbonitriles were synthesised by the reaction of substituted cinnamonitriles with 7-methoxy-2-tetralone using triethylbenzylammonium chloride (TEBA) as catalyst in aqueous media. The synthetic method has the advantages of good yields, less pollution, simple operation and being environment friendly. The structures of the products were identified by IR, 1H NMR and elemental analysis and confirmed by X-ray analysis.
