CuI functions as a mild Lewis acid catalyst to promote the condensation and cyclization reaction of 2-amino-N-(2-hydroxyphenyl)benzamide and 2-bromobenzaldehyde to build the quinazoline moiety first. With the addition of CsCO, it also can catalyse the subsequent intramolecular Ullmann type reaction to give 16H-dibenzo[2,3:6,7][1,4]oxazepino[5,4-b]quinazolin-16-ones in good yields.
CuI 作为一种温和的路易斯酸催化剂,可促进 2-氨基-N-(2-羟基苯基)苯甲酰胺和 2-溴苯甲醛的缩合和环化反应,首先构建喹唑啉部分。加入 CsCO₃ 后,它还可以催化随后的分子内 Ullmann 型反应,以高产率得到 16H-二苯并[2,3:6,7][1,4]氧氮杂卓[5,4-b]喹唑啉-16-酮。
