  钌催化的醚选择性氢硼水解

  摘要：

  HBpin的钌催化反应与取代有机醚导致的C-O键的激活，导致通过加氢形成烷烃和硼酸酯的boronolysis。使用钌预催化剂[Ru（对-cymene）Cl] 2 Cl 2（1），反应在135°C和大气压（135°C时约1.5 bar）的纯净条件下进行。不对称的二苄基醚在电子相对较差的C-O键上进行选择性氢硼水解。在芳基苄基或烷基苄基醚中，C O键裂解选择性地发生在C Bn -OR键上（Bn =苄基）；在烷基甲基醚中，C Me的选择性解构-OR键导致形成烷基硼酸酯和甲烷。环醚也适合催化氢硼水解。机制研究表明在单hydridobridged双核钌络合物原位形成立即[{（η 6 - p -cymene）的RuCl} 2（μ-H-μ-Cl）的（2），它是高活性的用于水力boronolysis醚。随着时间的流逝，双核物质分解产生钌纳米颗粒，该钌纳米颗粒也对该转化具有活性。使用这种催化系统，氢硼分解

  Expanded Substrate Scope and Improved Reactivity of Ether-Forming Cross-Coupling Reactions of Organotrifluoroborates and Acetals

  摘要：

  Mixed acetals and organotrifluoroborates undergo BF3 center dot OEt2-promoted cross-couplings to give dialkyl ethers under simple, mild conditions. A survey of reaction partners identified a hydroxamate leaving group that improves the regioselectivity and product yield in the BF3 center dot OEt2-promoted coupling reaction of mixed acetals and potassium alkynyl-, alkenyl-, aryl- and heteroaryltrifluoroborates to access substituted dialkyl ethers. This leaving group enables the reaction to proceed rapidly under mild conditions (0 degrees C, 5-60 min) and permits reactions with electron-deficient potassium aryltrifluoroborates that are less reactive with other acetal substrates. A study of the reaction mechanism and characterization of key intermediates by NMR spectroscopy and X-ray crystallography identified a role for the hydroxamate moiety as a reversible leaving group that serves to stabilize the key oxocarbenium intermediate and the need for a slight excess of organodifluoroborane to serve as a catalyst. A secondary role for the boron nucleophile as an activating ligand was also considered. These studies provide the basis for a general class of reagents that lead to dialkyl ethers by a simple, predictable cross-coupling reaction.

  日期：——

  with ethyl acetate as the solvent. A simple iron- and silyl chloride catalyzed method for the preparation of symmetrical and nonsymmetrical ethers is presented. Various aldehydes and ketones were reductively etherified by using triethylsilane as a reducing agent in the presence of 2 mol% of iron(III) oxo acetate and 8 mol% of chloro(trimethyl)silane. The reactions can be carried out at ambient temperatures

  The present invention is directed to a method for continuous production of dihydroartemisinin and also artemisinin derivatives derived from dihydroartemisinin by using artemisinin or dihydroartemisinic acid (DHAA) as starting material as well as to a continuous flow reactor for producing dihydroartemisinin as well as the artemisinin derivatives. It was found that the reduction of artemisinin to dihydroartemisinin in a continuous process requires a special kind of reactor and a special combination of reagents comprising a hydride reducing agent, at least one activator such as an inorganic activator, at least one solid base, at least one aprotic solvent and at least one C1-C5 alcohol.
