novel one-pot synthetic route to the poorly studied 4-heteroaryl-1,2-dihydro-3-benzazepine motif from 3,4-dihydroisoquinolinium compounds is described. The synthetic approach is based on heterocyclic ring expansion of isoquinoline substrates upon reaction with chloromethyl-substituted heterocycles. The scope and limitations of the reaction were investigated to give a series of novel heteroaryl-3-benzazepines
描述了一种新颖的一锅合成路线,该路线可从3,4-二氢异喹啉鎓化合物转变为研究较少的4-杂芳基-1,2-二氢-3-苯并ze庚因基序。合成方法基于异喹啉底物与氯甲基取代的杂环反应后的杂环扩环。研究了反应的范围和限制,得到了一系列新型的杂芳基-3-苯并b庚因。
