domino reaction of N-(2-benzimidazolyl)-2-aminobenzamide and 2-halogenated benzaldehyde has been studied. The procedure is based on a sequential CuI-catalyzed Ullmann reaction (C–N bond formation) and two bond cleavage reactions and provides an efficient strategy for the synthesis of benzimidazo[1,2-a]quinazolines catalyzed by CuI/l-proline.
研究了N-(2-苯并咪唑基)-2-氨基苯甲酰胺与2-卤代苯甲醛的铜(I)催化的多米诺反应。该方法基于顺序的CuI催化的Ullmann反应(C–N键形成)和两个键裂解反应,为CuI / 1-脯氨酸催化的苯并咪唑并[1,2- a ]喹唑啉合成提供了有效的策略。
