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
本文报道了一种高效的铜(I)催化体系,可将1,1-双[(频哪醇)硼基]烷烃非对映和对映选择性1,2加成到受保护的亚胺上,从而提供具有连续合成价值的对映体富集的β-氨基硼化合物立体定向中心。该反应在受保护的亚胺和1,1-双[(频哪醇)硼基]烷烃方面具有广阔的应用前景,因此可提供具有出色的非对映异构和对映选择性的β-氨基硼酸酯。还证明了所获得的β-氨基硼酸酯的合成效用。
