3 or benzoylacetonitrile 4 under microwave irradiation in dry media yields the 6-cyano-5,8-dihydropyrido[2,3-d]-pyrimidinones 5a-t. The structure of the synthesized compounds was determined on the basis of nmr measurements, especially by 1H,1H−, 1H,13C COSY, DEPT and NOESY experiments. In contrast with other pyrido-[2,3-d]pyrimidine derivatives, these compounds did not show any antifungal in vitro activity
在干燥介质中微波辐射下6-氨基嘧啶-4-酮1与苯甲醛2和β-氨基巴豆腈3或苯甲酰基乙腈4的反应产生6-氰基-5,8-二氢吡啶并[2,3- d ]-嘧啶酮5a- Ť。合成的化合物的结构是根据nmr测量确定的,尤其是通过1 H,1 H-,1 H,13 C COSY,DEPT和NOESY实验确定的。与其他吡啶基-[2,3- d ]嘧啶衍生物相比,这些化合物在250μg/ mL时未显示任何抗真菌体外活性。
