Reported herein is an efficient copper(I)‐catalytic system for the diastereo‐ and enantioselective 1,2‐addition of 1,1‐bis[(pinacolato)boryl]alkanes to protected imines to afford synthetically valuable enantioenriched β‐aminoboron compounds bearing contiguous stereogenic centers. The reaction exhibits a broad scope with respect to protected imines and 1,1‐bis[(pinacolato)boryl]alkanes, thus providing
