Rh( iii )-Catalyzed chemo-, regio- and stereoselective carboamination of sulfonyl allenes with N -phenoxy amides or N -enoxy imides

The Rh( iii )-catalyzed chemo-, regio- and stereoselective carboamination of sulfonyl allenes has been realized by virtue of either N -phenoxy amides or N -enoxy imides simultaneously acting as the C- and N-sources, via redox-neutral tandem C–H activation/allene insertion/oxidative addition/C–N bond formation for the direct construction of allylamine derivatives equipped with an α-quaternary carbon center. This protocol features high atom-economy with good substrate compatibility and exhibits profound synthetic potential for late-stage C–H modification of complex molecules.
