Abstract

CuI/l-proline-catalyzed cross-coupling of 2-halotrifluoroacetanilides with β-keto esters and amides followed by acidic hydrolysis delivered 2,3-disubstituted indoles. 2-halotrifluoroacetanilides bearing a strong electron-withdrawing group in the 4-position can undergo in situ basic hydrolysis to provide the corresponding indoles.
