An efficient cascade protocol for the stereoselective synthesis of borylated carbocycles via copper-catalyzed borylative Michael/Michael cyclization is presented. Using this mild approach, up to 24 new boronic ester substituted indanes, cyclohexanes, and cyclopentanes were prepared in good yields with excellent diasteroselectivities and exceptional functional group tolerance. Furthermore, carbacyclic
