Abstract: | A facile microwave‐assisted synthesis of pyrano2,3‐d]pyrimidines derivatives is accomplished via reactions of 4‐arylmethylene‐2‐phenyloxazol‐5(4H)‐ones with pyrimidine‐4,6‐diol in ethylene glycol. The reaction is simple to perform and occurs under mild conditions with broad scope of applicability. |
