of methyl aluminum complexes bearing chiral biphenol-type ligands were found to be highly active catalysts in the asymmetric reduction of heterocyclic ketones (S/C = 100 - 500, ee up to 99%). The protocol is suitable for a wide range of substrates and has a high tolerance to functional groups. The formed 2-heterocyclic-alcohols are valuable building blocks in drug discovery or can be used as ligands
发现一系列带有手性双酚型配体的甲基铝配合物是杂环酮不对称还原的高活性催化剂(S/C = 100 - 500,ee 高达 99%)。该协议适用于广泛的底物,并且对官能团具有很高的耐受性。形成的 2-杂环醇是药物发现中的重要组成部分,或可用作不对称催化中的配体。反应中间体的分离和综合表征支持 DFT 计算提出的催化循环。
