  通过硼酸选择性相转移实现芳基有机硼系统的化学选择性氧化†

  摘要：

  我们报道了含有两个可氧化硼基团的芳基有机硼系统的直接化学选择性布朗型氧化。碱性双相反应条件能够在硼酸频哪醇 (BPin) 酯存在下选择性形成硼酸三羟基硼酸酯并进行相转移，同时避免形态平衡。光谱研究验证了有机硼物质的碱促进相选择性辨别。这种现象在多种有机硼化合物中普遍存在，也可用于反转传统的保护基策略，使 BMIDA 物质能够在通常更具反应性的 BPin 底物上进行化学选择性氧化。我们还证明了二硼酸系统的选择性氧化具有可先验预测的化学选择性。该方法的实用性通过化学选择性氧化亲核试剂偶联的开发来例证。

  摘要：

  芳基硼酸作为试剂和目标结构在各种有用的应用中变得越来越重要。最近，报道了使用原子经济的四羟基二硼（BBA）试剂在钯催化下合成芳基硼酸。钯的高成本，加上钯和铜催化工艺的一些限制，促使我们开发一种替代方法。因此，已经制定了使用四羟基二硼（BBA）对芳基和杂芳基卤化物和拟卤化物进行镍催化的硼基化反应。该反应被证明具有广泛的官能团耐受性并适用于许多杂环体系。据我们所知，这里提供的例子代表了在室温下进行的唯一有效的镍催化宫浦硼化反应。

  reaction of aryl bromides. Bis-boronic acid (BBA), was used, and the borylation reaction was performed using a simple procedure at a mild temperature. Under mild conditions, aryl bromides were converted to arylboronic acids directly without any deprotection steps and purified by conversion to trifluoroborate salts. The functional group tolerance was considerably high. The mechanism study suggested that

  在这项研究中，我们开发了一个简单的无过渡金属的芳基溴化物的无硼化反应。使用双硼酸（BBA），并通过简单的步骤在温和的温度下进行硼酸酯化反应。在温和的条件下，不进行任何脱保护步骤，将芳基溴化物直接转化为芳基硼酸，并通过转化为三氟硼酸盐进行纯化。功能组耐受性相当高。机理研究表明该硼酸酯化反应通过自由基途径进行。

  A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%-85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation-condensation protocol

  We herein report a Ni-catalyzed three-component coupling of 1,3-butadiene, carbonyl compounds, and arylboronic acids as a general synthetic approach to 1,4-disubstituted homoallylic alcohols, an important class of compounds, which have previously not been straightforward to access. The reaction occurs efficiently using a Ni(cod)2 catalyst without any external base and ligand at ambient temperature
