Transition metal‐catalyzed site‐ and stereoselective C−H activation of strained (hetero)cycloalkanes remains a formidable challenge. We herein report a carbamate‐directed iridium‐catalyzed asymmetric β−C(sp3)−H borylation of cyclopropanol derivatives. A variety of densely functionalized cyclopropanols were obtained in good enantioselectivities via desymmetrization and kinetic resolution. In addition,...
