The unprecedented title reaction between glycinederivatives and indoles, as well as the auto‐oxidative Povarov/aromatization tandem reaction of glycinederivatives with olefins are described. The reactions were performed in the absence of redox‐active catalysts and chemical oxidants under mild reaction conditions. Only simple organic solvents and air (or O2) were required.
AbstractA simple and efficient copper(I) chloride‐catalyzed aerobic oxidative coupling of glycine derivatives (glycine esters, glycine amides and short peptides) with indoles has been developed. The reaction is performed in the absence of any other additives under mild conditions and only requires simple copper salts as a catalyst and oxygen as a co‐oxidant.magnified image
