Abstract

A green and biodegradable carbohydrate-derived alkylamine was designed and employed as ligand for Ullmann type C–N coupling catalyzed by copper in water. The coupling of aryl iodide and N-nucleophiles were examined and moderate to excellent yields were obtained. In addition, the in-water coupling strategy was expanded successfully to the reaction of indoles with 4-iodoanisole. By measuring the solubility, it is speculated that carbohydrate-derived alkylamine plays the role of chelating copper and promoting the dissolution of 4-iodoanisole in water. Remarkably, this methodology was environmentally friendly and economical because of the use of aqueous media in place of organic solvents.
