Abstract Reported here is an efficient and simple ether‐directed iridium‐catalyzed enantioselective C( sp 3 )−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.
