Rh(III)-Catalyzed sulfonylamination of α-indolyl alcohols via Csp2–Csp3 bond cleavage

A Rh(III)-catalyzed beta-carbon amination of α-aryl alcohols with sulfonyl azides has been developed. This transformation features unstrained Csp2–Csp3 σ bond amination via C–C σ bond cleavage, and provides a direct approach to complex 2-aminoindoles.
