  Synthesis and Structure−Activity Studies of Novel Orally Active Non-Terpenoic 2,3-Oxidosqualene Cyclase Inhibitors

  摘要：

  New orally active non-terpenoic inhibitors of human 2,3-oxidosqualene cyclase (hOSC) are reported. The starting point for the optimization process was a set of compounds derived from a fungicide project, which in addition to showing high affinity for OSC from Candida albicans showed also high affinity for human OSC. Common structural elements of these inhibitors are an amine residue and an electrophilic carbonyl C atom embedded in a benzophenone system, which are at a distance of about 10.7 Angstrom. Considering that the keto moiety is in a potentially labile position, modifications of the substitution pattern at the benzophenone as well as annelated heteroaryl systems were explored. Our approach combined testing of the compounds first for increased binding affinity and for increased stability in vitro. Most promising compounds were then evaluated for their efficacy in lowering plasma total cholesterol (TC) and plasma low-density lipoprotein cholesterol (LDL-C) in hyperlipidemic hamsters. In this respect, the most promising compounds are the benzophenone derivative 1.fumarate and the benzo[d]-isothiazol 24.fumarate, which lowered TC by 40% and 33%, respectively.

  钯（II）催化的芳基亚磺酸钠和腈的芳基酮的脱硫合成：范围，局限性和机理研究

  摘要：

  已经开发了一种快速有效的方案，在受控的微波辐射下，钯（II）催化从芳基亚磺酸钠和各种有机腈生产芳基酮。通过结合14个芳基亚磺酸钠和21个腈给出55个芳基酮实例，证明了该反应的广泛范围。另一个实例说明，通过选择腈反应物，苯并呋喃也是可得到的。通过电喷雾电离质谱和DFT计算研究了反应机理。还比较了从腈的脱硫合成芳基酮与从苯甲酸开始的相应转化。能量分布图的比较表明，2的脱羧所需的自由能 6-二甲氧基苯甲酸，尤其是苯甲酸比用于生成关键的芳基钯中间体的相应的脱硫方法要高。通过ESI-MS和DFT计算检测到的钯（II）中间体对催化循环提供了详细的了解。

• Dirhodium‐Catalyzed Enantioselective B−H Bond Insertion of <i>gem</i> ‐Diaryl Carbenes: Efficient Access to <i>gem</i> ‐Diarylmethine Boranes

  We report highly enantioselective dirhodium-catalyzed B−H bond insertion reactions with diaryl diazomethanes as carbene precursors. These reactions afforded chiral gem-diarylmethine borane compounds in high yield (up to 99 % yield), high activity (turnover numbers up to 14 300), high enantioselectivity (up to 99 % ee) and showed unprecedented broad functional group tolerance.

  enantioselection usually depends on differences in steric interactions between prochiral substrates and a chiral catalyst. We have discovered a carbene Si-H insertion in which the enantioselectivity depends primarily on the electronic characteristics of the carbene substrate, and the log(er) values are linearly related to Hammett parameters. A new class of chiral tetraphosphate dirhodium catalysts was developed

  催化对映选择通常取决于前手性底物和手性催化剂之间空间相互作用的差异。我们发现了一种卡宾 Si-H 插入，其中对映选择性主要取决于卡宾底物的电子特性，并且 log(er) 值与哈米特参数线性相关。开发了一类新的手性四磷酸二铑催化剂，该催化剂在二芳基卡宾插入硅烷的 Si-H 键方面表现出优异的活性和对映选择性。计算和机械研究表明卡宾的两个芳基之间的电子差异如何导致非对映过渡态能量的差异。该研究为利用基材的电子特性进行不对称催化提供了一种新策略。

  日期：——

  diversely substituted 2-aroylbenzoate esters featuring a new protocol for the carbonylative coupling of aryl bromides with boronic acids and a new strategy to favour carbonylative over non-carbonylative reactions. Two different synthetic pathways - (i) the alkoxycarbonylation of 2-bromo benzophenones and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters - were evaluated. The latter approach

  我们已经开发出一种羰基化方法，用于合成不同取代的2-芳基苯甲酸酯，其特征是芳基溴化物与硼酸进行羰基化偶联的新方案，以及采用羰基化而非非羰基化反应的新策略。评估了两种不同的合成途径-（i）2-溴二苯甲酮的烷氧基羰基化和（ii）2-溴苯甲酸酯的羰基化Suzuki-Miyaura偶联-。后一种方法提供了更宽的基材耐受性，因此是首选途径。我们观察到2-取代的芳基溴化物是具有挑战性的羰基化化学底物，有利于非羰基化途径。但是，我们发现，缓慢添加硼酸可以改善羰基化的Suzuki-Miyaura偶联，
