  BF₃·OEt₂-Mediated Highly Regioselective S_N2-Type Ring-Opening of N-Activated Aziridines and N-Activated Azetidines by Tetraalkylammonium Halides

  摘要：

  A highly regioselective Lewis acid-mediated S(N)2-type ring-opening of N-sulfonylaziridines and azetidines with tetraalkylammonium halides in CH2Cl2 solution to afford 1,2- and 1,3-haloamines in excellent yields is described. An easy diastereoselective route toward substituted chiral N-tosylaziridines has been developed. The mechanism of ring-opening via S(N)2 pathway has been confirmed by the formation of chiral haloamines with excellent er and dr. Chloroamines obtained from 2,3-disubstituted aziridines were converted to the chiral N-tosylamines via radical dehalogenation.

  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。
