pyrazole‐directed iridium‐catalyzedenantioselectiveborylation of unbiased methylene C−H bonds at the position β to a nitrogen center. The combination of a chiral bidentate boryl ligand, iridium precursor, and pyrazole directing group was responsible for the high regio‐ and enantioselectivity observed. The method tolerated a vast array of functional groups to afford the corresponding C(sp3)−H functionalization
