Abstract: Abstract This article describes an efficient method for the synthesis of pyrano[2,3-d]pyrimidinones and pyrido[2,3-d]pyrimidines via promotion of the condensation of aromatic aldehydes, malononitrile and barbituric acid and/or 6-amino-1,3-dimethyluracil in the presence of poly(4-vinylpyridine).
