  Preparative access to medicinal chemistry related chiral alcohols using carbonyl reductase technology

  摘要：

  Libraries of highly enantioenriched secondary alcohols in both enantiomeric forms were synthesised by enzymatic reduction of their parent ketones using selectAZyme (TM) carbonyl reductase (CRED) technology. Commercially available CREDs were able to reduce a range of substrate classes efficiently and with very high enantioselectivity. Matching substrate classes to small subsets of CREDs enabled the fast development of preparative bioreductions and the rapid generation of 100-1500 mg samples of chiral alcohols in typically >95% ee and the majority in >= 99.0% ee. The conditions for small scale synthesis were then scaled up to 0.5 kg to deliver one of the chiral alcohols, (S)-1-(4-bromophenyl)-2-chloroethanol, in 99.8% ee and 91% isolated yield.

  The asymmetric hydrogenation of 2,2,2-trifluoroacetophenones and aryl perfluoroalkyl ketones was developed using a unique, well-defined chloride-bridged dinuclear rhodium(III) complex bearing Josiphos-type diphosphine ligands. These complexes were prepared from [RhCl(cod)]2 , Josiphos ligands, and hydrochloric acid. As catalyst precursors, they allow for the efficient and enantioselective synthesis

  2，2，2-三氟苯乙酮和芳基全氟烷基酮的不对称氢化反应是使用独特的，定义明确的带有Josiphos型二膦配体的氯桥联二核铑（III）络合物开发的。这些配合物是由[RhCl（cod）] 2，Josiphos配体和盐酸制备的。作为催化剂的前体，它们允许具有全氟烷基的手性仲醇的有效和对映选择性合成（最高99％ee）。该系统不需要用于2,2,2-三氟苯乙酮氢化的活化碱。另外，首次报道了2-苯基-3-（卤代乙酰基）吲哚的对映选择性C ＝ O氢化，这是药物化学中的一类特权结构。

  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.
