A new method is presented for the synthesis of 2-aminoquinazolines, which is based on a Chan–Evans–Lam coupling of (2-formylphenyl)boronic acids with guanidines. Relatively mild conditions involving the use of inexpensive CuI as a catalyst and methanol as a solvent permit the application of the method to a wide range of substrates. Nonsubstituted, N-monosubstituted, and N,N-disubstituted guanidines
提出了一种合成 2-氨基喹唑啉的新方法,该方法基于(2-甲酰基苯基)硼酸与胍的 Chan-Evans-Lam 偶联。涉及使用廉价的 CuI 作为催化剂和甲醇作为溶剂的相对温和的条件允许该方法应用于广泛的基材。未取代的、N-单取代的和 N,N-二取代的胍可用作反应物,以从容易获得的(2-甲酰基苯基)硼酸以中等产率得到相应的 2-氨基喹唑啉。
