two-step process involves initial microwave-assisted amide bond formation between 2-halo-arylacetic acids and various alkylamines and anilines, followed by a palladium-catalyzed intramolecular amidation under aqueous conditions. In the case of alkylamines, the procedure can be carried out as a one-pot process without isolation of the intermediate amide. [structure: see text]
已经开发了用于合成N-取代的羟吲哚的通用方法。此两步过程涉及在2-卤代芳酸与各种烷基胺和苯胺之间首先形成微波辅助的酰胺键,然后在水性条件下进行钯催化的分子内酰胺化反应。在烷基胺的情况下,该过程可以一锅法进行,而无需分离中间体酰胺。[结构:见文字]
