A Brønsted acid-catalyzed addition of 2-alkylazaarenes to in situ generated N-sulfonylimines through selective C(sp3)–H bond functionalization has been developed. This protocol provides an atom- and step-economic approach to α-substituted sulfonamides.

The Lewisacid-catalyzed CH functionalization of 2-substituted azaarenes with N-sulfonylaldimines has been developed, which provides a rapid and efficient approach for synthesis of heterocycle-containing isoindolinones and isoindolines.
