A series of novel substituted 2-amino-4H-benzo[h]chromene-3-carbonitrile derivatives was synthesised by condensation of different halogen derivatives with the hydroxy-group of 2-amino-8-hydroxy-4-styryl- 4H-benzo[h]chromene-3-carbonitrile and 2-amino-8-hydroxy-4- phenethyl-4H-benzo-[h]chromene-3-carbonitrile, which were prepared from cinnamaldehyde, malononitrile and naphthalene-1,6-diol through Knoevenagel condensation and cyclization reaction and then reduction with hydrogen in the presence of Pd/C at room temperature. Each intermediates and target compounds were obtained in good yields. |
