We have developed a versatile and efficient method for copper-catalyzed synthesis of both 2-amino-4(3H)-quinazolinone and 2-aminoquinazoline derivatives. The protocol uses readily available substituted 2-halobenzoic acids, 2-bromobenzaldehyde, 2-bromophenyl ketones and guanidines as the starting materials, inexpensive copper(I) iodide as the catalyst, and the method has important application values
我们已经开发了一种通用且有效的方法,用于铜催化的2-氨基-4(3H)-喹唑啉酮和2-氨基喹唑啉衍生物的合成。该方案使用容易获得的取代的2-卤代苯甲酸,2-溴苯甲醛,2-溴苯基酮和胍作为起始原料,廉价的碘化亚铜(I)作为催化剂,该方法对于在N-杂环结构中的应用具有重要的应用价值。有机化学和药物化学。 铜催化-交叉偶联-2-氨基-4(3H)-喹唑啉酮-2-氨基喹唑啉-合成方法
