A simple, efficient, and facile synthetic route for the preparation of indole-2-carboxylic esters was described. The cascade reactions of 2-bromobenzaldehyde and glycine ester hydrochloride were promoted by Cu2O and a base to provide the corresponding products in good yields. Commercially available, inexpensive substrates and reagents were employed under mild reaction conditions in this one-pot operation
描述了用于制备吲哚-2-羧酸酯的简单、有效和简便的合成路线。Cu2O和碱促进2-溴苯甲醛和甘氨酸酯盐酸盐的级联反应,以良好的收率提供相应的产物。在这种一锅操作中,在温和的反应条件下使用了市售的廉价底物和试剂,这与现有的获得 2-取代吲哚的方法相辅相成。
