atroposelective coupling of indoles with chiral amino acid-based sulfonamides mediated by hypohalides is described. A series of 2-amido-3-haloindoles with a C–N chiral axis are delivered using this strategy. The C3 halogen atoms can facilitate further transformation. Various functionalities, such as carbonyl, phosphine, aryl, and alkenyl groups, can be introduced into the C3 position of indoles. These structurally

NaClO-promoted couplings of 3-substituted indoles with chiral amino acid-based sulfonamides. A series of structurally diverse N-indole sulfonamide-based atropisomers were prepared using this established method. The stability of these structurally interesting atropisomers highly relied on the C3-substituents of indoles and side chains of amino acidderivatives.
