摘要

我们开发了通过ritter型反应合成咪唑[1,5-a]吡啶和苯氮平类似物的新方法。这些方法利用铋（III）三氟甲烷磺酸盐（Bi(OTf)3）与对甲苯磺酸（p-TsOH·H2O）结合，这是一种将苯基醇转化为苯基阳离子的有效催化剂。该程序提供了广泛的衬底范围，并提供所需的产品，产量范围从中等到优异。

Strategic Methodologies for Efficient Synthesis of Imidazo[1,5-a]pyridine and Benzazepine Analogs via the Unique Ritter-Type Reaction

We have developed novel approaches for synthesizing imidazo[1,5-a]pyridine and benzazepine analogs through a Ritter-type reaction. These methods utilize bismuth(III) trifluoromethanesulfonate (Bi(OTf)₃), an efficient catalyst for converting benzylic alcohol into benzylic cations, in combination with para-toluenesulfonic acid (p-TsOH·H₂O). The procedures offer a wide substrate scope and deliver the desired products in yields ranging from moderate to excellent.
