Rhodium-Catalyzed Atroposelective Construction of Indoles via C?H Bond Activation

Article abstract of DOI:10.1002/anie.202012932

Reported herein is the rhodium(III)-catalyzed C?H activation of anilines bearing an N-isoquinolyl directing group for oxidative [3+2] annulation with four classes of internal alkynes, leading to atroposelective indole synthesis via dynamic kinetic annulation with C-N reductive elimination constituting the stereo-determining step. This reaction proceeds under mild conditions with high regio- and enantioselectivity and functional group compatibility.
