摘要：

The multicomponent condensation of 2-thiobarbituric acid, aldehydes, malononitrile or ethyl cyanoacetate, alkyl halides and morpholine was studied. It is shown that the condensation products are substituted 2-alkylthio-7-amino-6-cyano(ethoxycarbonyl)-5H-pyrano- [2,3-d]pyrimidines. The products were characterized by IR and NMR spectroscopy and elemental analysis.
