Simple ether-directed enantioselectiveC(sp3)−Hborylation of cyclopropanes was accomplished by CBL/iridium catalysis for the first time. The reported method features tolerance of a broad range of functional groups (38 examples), excellent enantioselectivity (up to 99 % ee), and high turnover numbers (up to 335).
