A highly ef?cient synthesis of novel pyrido[2,3‐d]pyrimidin‐4‐ols was developed via an iodine‐catalyzed tandem oxidative cyclization under focused microwave irradiation. Pyrido[2,3‐d]pyrimidin‐4‐ols were obtained from easily available 2‐amino‐4‐aryl‐6‐arylnicotinamides and benzylic amines with good to excellent yields.
在聚焦微波辐射下,通过碘催化的串联氧化环化反应开发了高效的新型吡啶并[2,3 - d ]嘧啶-4-醇。从容易获得的2-氨基-4-芳基-6-芳基烟酰胺和苄基胺中制得Pyrido [2,3 - d ]嘧啶-4-醇,收率好至极好。
