Starting from simple anilines and ester arylpropiolates, an efficient one-pot synthesis of 2-arylindole-3-carboxylate derivatives has been developed through copper-mediated sequential hydroamination and cross-dehydrogenative coupling (CDC) reaction. The initial hydroamination of anilines to ester arylpropiolates in benzene can proceed in a stereoselective manner to give ester (Z)-3-(arylamino)acrylates

one-step synthesis of 2,3-disubstitutedindoles from readily available starting materials, 2-iodoaniline and various β-keto esters was described. The advantage of this method is the use of cheap catalysts and simple experimental procedures undermild reaction conditions. As the substituted indole derivatives are important starting materials for the synthesis of biologically active indole alkaloids
