  Photo-irradiation of α-halo carbonyl compounds: a novel synthesis of α-hydroxy- and α,α′-dihydroxyketones

  摘要：

  The reaction of g.-halo ketones (alpha-iodocycloalkanones, alpha-bromocycloalkanones, alpha-iodo-beta-alkoxy esters, and alpha-iodoacyclic-ketones) with irradiation under a high-pressure mercury lamp gave the corresponding alpha-hydroxyketones in good yields. For alpha-bromoketones, it was found that alpha-hydroxylation does not occur. However, alpha-bromoketones were convened into a-hydroxyketones in the presence of KI. In the case of alpha,alpha(1)-diiodo ketones, alpha,alpha(1)-dihydroxyketones, which up to now have scarcely been reported, were obtained. This reaction affords a new, clean and convenient synthetic method for alpha-hydroxy- and alpha,alpha(1)-dihydroxyketones. (C) 2005 Elsevier Ltd. All rights reserved.

• Complementary and selective oxidation of hydrocarbon derivatives by two cytochrome P450 enzymes of the same family
  作者：Md. Raihan Sarkar、Stephen G. Bell

  DOI：10.1039/d0cy01040e

  日期：——

  The cytochrome P450 enzymes CYP101B1 and CYP101C1, which are from the bacterium Novosphingobium aromaticivorans DSM12444, can hydroxylate norisoprenoids with high activity and selectivity. With the goal of expanding and establishing their substrate range with a view to developing applications, the oxidation of a selection of cyclic alkanes, ketones and alcohols was investigated. Cycloalkanes were oxidised

  细胞色素P450酶CYP101B1和CYP101C1，来自细菌新孢子虫DSM12444可高活性和选择性地羟基化类异戊二烯。为了扩展和建立其底物范围，以开发应用，研究了选择环烷烃，酮和醇的氧化。环烷被氧化，但两种酶均显示出中等的结合亲和力和较低的生产活性。我们通过将组氨酸残基切换为苯丙氨酸（H85F），使活性位点更具疏水性，从而改善了这些底物与CYP101B1的结合和活性。环烷烃骨架中酮部分的存在显着改善了两种酶的氧化活性。CYP101C1优选在C-2位置催化环烷酮的氧化，而CYP101B1在远离羰基的位置以较高的生产率氧化这些底物。这表明每种酶的活性位点中环酮的结合方向必须不同。线性酮也被两种酶氧化，但活性和选择性较低。CYP101B1比CYP101C1更有效地氧化具有酯导向基团的环状底物。两种酶都在远离酯导向基团的环系统上以高区域选择性催化这些酯的氧化。CYP101C1比CYP101B1
• Oxidation of Allenes and Alkynes with Hydrogen Peroxide Catalyzed by Cetylpyridinium Peroxotungstophosphate (PCWP)

  The oxidation of allenes and alkynes with hydrogen peroxide catalyzed by peroxotungstophosphate (PCWP) was examined. A variety of allenes were first converted into the corresponding alpha-ethoxy ketones upon treatment with 35% H2O2 under the influence of PCWP in a mixed solvent consisting of ethanol and dichloromethane. When the reaction was carried out using tert-butyl alcohol as a solvent, approximately a 1:1 regioisomeric mixture of alpha-hydroxy ketones was obtained along with a small amount of alpha-tert-butoxy ketone. Oxidation of internal alkynes such as 4-octyne by the PCWP-H2O2 system under phase-transfer conditions using chloroform produced alpha,beta-epoxy ketones in good yields. The same reaction in a mixed solvent of ethanol and chloroform gave alpha,beta-unsaturated ketones rather than alpha,beta-epoxy ketones. Plausible reaction paths are proposed for the oxidation of allenes and alkynes by the PCWP-H2O2 system.

  日期：1997.10

  Acid chlorides react with esters in the presence of samarium diiodide and catalytic amounts of NiI2 to afford samarium enediolates which can further react with electrophiles such as water or aldehydes to give respectively alpha-ketols or alpha-dihydroxyketones.
