Abstract

The first example of the sulfinylation of indoles with arylsulfinamides in water in the presence of trifluoroacetic acid as a promoter is described. The reaction occurs smoothly at room temperature under environmentally benign conditions without any catalyst, additive, ligand, or organic solvent. The developed sulfoxide synthetic protocol is attractive due to the use of water as the solvent and provides a novel and efficient route to a wide range of functionalized diaryl sulfoxides.

3-(芳烃亚磺酰基)吲哚在水中的高效合成

摘要

描述了在三氟乙酸作为促进剂存在下，在水中用芳基亚磺酰胺对吲哚进行亚磺酰化的第一个例子。该反应在室温、环境友好的条件下顺利进行，无需任何催化剂、添加剂、配体或有机溶剂。由于使用水作为溶剂，开发的亚砜合成方案很有吸引力，并为广泛的功能化二芳基亚砜提供了一种新颖有效的途径。
