An efficient one-step method to access 4(3H)quinazolinimines by reaction of phenylchloroimines with 2-aminobenzonitrile is described. The reaction of (E)-N-(2-cyanophenyl)benzimidoyl chloride with substituted anilines that yields a number of their corresponding C2, N3-substituted quinazoliniminium chlorides or neutral products is also reported. These methods provide direct and flexible access to diverse
描述了一种有效的一步法,通过苯氯亚胺与2-氨基苄腈的反应来获得4(3 H)喹唑啉亚胺。还报道了(E)-N-(2-氰基苯基)苯甲酰亚胺基氯与取代的苯胺的反应,其产生许多相应的C 2,N 3取代的喹唑啉亚胺氯化物或中性产物。这些方法提供了直接和灵活的途径,以获取在C2,N3位取代的各种取代的亚氨基喹唑啉。所有新化合物均经过充分表征,并给出了六个具有单晶X射线结构的示例。
