One-pot Synthesis of 2-Amino-3-cyano-4-aryl-4H-benzo[h]chromenes
Abstract:
A series of 2-amino-3-cyano-4-aryl-4H-benzo[h]chromenes were synehesized by the reaction of malononitrile and 1-naphthol with corresponding aromatic aldehydes in ethanol in the presence of piperidine as catalyst. The structures of all compounds obtained were characterized by elemental analysis, IR, 1H NMR and single crystal X-ray diffractometry. X-ray crystal structure analysis indicates compound 4b crystallizes in monoclinic, with space group C2/c, a=2.4221(6) nm, b=0.9016(2) nm, c=1.7003(5) nm, U=93.16(1)°, V=3.7074(15) nm3, Z=8, Dc=1.284 g/cm3, I≥2e(I)=2141, R=0.0432, wR=0.1085. Compared to other methods, this method has the advantages of simple operation and good yields.
