Abstract

The reaction of 6‐aminopyrimidin‐4‐ones 1 with benzaldehydes 2 and β‐aminocrotononitrile 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 up to 250 μg/mL.
