transformations of N-sulfonyl-4-(2-(ethynyl)aryl)-1,2,3-triazoles with various generated in situ or external nucleophiles by means of silver catalysis for producing diverse functionalized isoquinolines is described. Mechanistically, the reaction is proposed to involve a key silver carbenoid intermediate, thus enabling the formation of multiple chemical bonds via ring opening, N2 extrusion, silver carbenoid
描述了通过银催化以产生各种官能化的异喹啉的方式,将N-磺酰基-4-(2-(乙炔基)芳基)-1,2,3-三唑转化成具有原位或外部亲核试剂的各种方法。从机理上讲,该反应被提出涉及关键的银类类胡萝卜素中间体,因此能够通过开环,N 2挤出,银类类胡萝卜素形成,亲核加成和复杂环空级联反应形成多个化学键。
