  Biocatalytic reduction of α-keto amides to (R)-α-hydroxy amides using Candida parapsilosis ATCC 7330

  摘要：

  Biocatalytic reduction of primary and secondary alpha-keto amides was accomplished using whole cells of Candida parapsilosis ATCC 7330. The primary (R)-alpha-hydroxy amides were obtained in good enantiomeric excess (up to 94%) and conversion (88-99%) as compared to the secondary (R)-alpha-hydroxy amides. (C) 2012 Elsevier B.V.

  A first example of diphenylborinic acid catalyzed α-addition to isocyanide with aldehyde and water is described. The reaction proceeded smoothly in the presence of water and 5 mol % of borinic acid to give the corresponding α-hydroxyamides in good to high yields. A wide range of aldehydes and isocyanides are applicable to this reaction.

  reaction. However, this catalytic process was limited. Herein, we report the first examples of 3,5,6-trifluoro-2-pyridone-catalyzed α-addition of isocyanides to aldehydes, in the presence of water in benzene, to provide α-hydroxyamides. Various aldehydes and isocyanides performed well in this reaction to provide the α-hydroxyamides. Even highly constrained substrates were well tolerated. The reaction

  α-羟基酰胺是一种重要的化学成分，广泛存在于具有生物活性的天然产物中。获取 α-羟基酰胺的最直接方法之一是 Passerini 型反应。然而，这种催化过程是有限的。在此，我们报告了在苯中存在水的情况下，3,5,6-三氟-2-吡啶酮催化的异氰化物与醛的α-加成反应以提供α-羟基酰胺的第一个例子。各种醛和异氰化物在该反应中表现良好以提供 α-羟基酰胺。即使是高度受限的底物也能被很好地耐受。该反应不受不方便的温度控制、惰性气氛或干燥溶剂的要求的限制。新的催化反应可能为开发异氰化物的不对称有机催化 α-加成开辟道路。

• 1-Chloroalkyl p-tolyl sulfoxides as useful agents for homologation of carbonyl compounds: conversion of carbonyl compounds to .alpha.-hydroxy acids, esters, and amides and .alpha.,.alpha.'-dihydroxy ketones

  日期：1991.6

  One-carbon homologation of carbonyl compounds to alpha-hydroxy acids, esters, and amides by the use of 1-chloroalkyl p-tolyl sulfoxide as a hydroxycarbonyl anion equivalent is reported. Oxidation of the vinyl chlorides, the intermediates of the above-mentioned method, with osmium tetraoxide gives alpha,alpha'-dihydroxy ketones which are found in biologically active natural products such as cortisone and adriamycin.
