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.
A selective functionalization of C–C═C bonds toward N–C═O bonds is realized by an n-Bu4NI-catalyzed reaction of 3-methylindoles with primaryamines using TBHP as the unique oxidant. The systematic process involves oxygenation, nitrogenation, ring-opening, and recyclization, affording a broad range of quinazolinones in good to excellent yields.
