Simple Ether‐Directed Enantioselective C(sp3)−H Borylation of Cyclopropanes Enabled by Iridium Catalysis

Abstract

Reported here is an efficient and simple ether-directed iridium-catalyzed enantioselective C(sp3 )-H borylation of cyclopropanes. Various functional groups were well-tolerated, affording a vast array of chiral cyclopropanes with high enantioselectivities. We also demonstrated that the turnover numbers of the current reaction could be up to 335.
