A series of pyrano[2,3-d]pyrimidine derivatives were synthesized by the reaction of aromatic aldehyde, malononitrile and 2-amino-4,6-dihydroxylpyrimidine in the presence of benzyltrimethyl ammonium bromide in water at 80 ℃. The structures of the products were characterized by IR, 1H NMR spectra and elemental analysis. Compared with other synthetic methods, this method has the advantages of neutral conditions, high yields and simple work-up procedures. In addition, water as a green solvent gave some merits such as cheapness, safty, and non-pollution.

Key words: benzyltrimethyl ammonium bromide, green synthesis, pyrano[2,3-d]pyrimidine
