  名称：

  Asymmetric trifluoromethylation of aromatic aldehydes by cooperative catalysis with (IPr)CuF and quinidine-derived quaternary ammonium salt

  摘要：

  已经开发了一种针对醛类的通用对映选择性三氟甲基化反应，使用(IPr)CuF和奎宁衍生的四价铵盐作为协同催化剂。因此，广泛的芳香醛被转化为相应的产物，产率高达92%，对映体过剩率（ee）为81%，催化剂用量为2摩尔百分比。显著增强的活性和对映选择性源于活性[(IPr)CuCF3]的初始生成以及其他铜物种的额外配位活化。

  A general catalytic enantioselective trifluoromethylation of aromatic aldehydes using (IPr)CuF and quinidine-derived quaternary ammonium salt as catalysts has been developed. A wide range of aromatic aldehydes are converted to the corresponding products in up to 92% yield and 81% ee at 2 mol% of catalyst loading. (C) 2013 Elsevier B.V. All rights reserved.

  The catalytic enantioselective trifluoromethylation reaction of aromatic aldehydes using the Ruppert-Prakash reagent (Me3SiCF3) has been disclosed, with an operationally simple procedure, based on the combination of sterically demanding cinchona alkaloid-derived phase-transfer catalyst 3b with tetramethylammonium fluoride (TMAF). Our methodology provides medicinally important alpha-trifluoromethyl alcohols with high chemical yields and moderate to good enantioselectivities (50-70% ee). (c) 2013 Elsevier B.V.
