  A Practical and Efficient Synthesis of 2,5-Disubstituted-3,5-dihydro-imidazol-4-ones from Oxazolones

  摘要：

  An alternative procedure for the synthesis of 2,5-disubstituted-3,5-dihydro-imidazol-4-ones from substituted oxazolones was evaluated. The initial oxazolone ring-opening reaction was examined with a variety of ammonia source compounds followed by the subsequent 3,5-dihydro-imidazol-4-one cyclization reaction, which was carried out with either an organic or inorganic base in aprotic solvents. In this article, we report the results of an efficient and straightforward procedure for the synthesis of 2,5-disubstituted-3,5-dihydro-imidazol-4-ones that gives satisfactory yield and quality.

  Hepatitis C infection is a cause of chronic liver diseases such as cirrhosis and carcinoma. The current therapy for hepatitis C has limited efficacy and low tolerance. The HCV encodes a serine protease which is critical for viral replication, and few protease inhibitors are currently on the market. In this paper, we describe the synthesis and screening of novel isosorbide-based peptidomimetic inhibitors

  丙型肝炎感染是慢性肝病（如肝硬化和癌）的原因。当前的丙型肝炎疗法疗效有限且耐受性低。HCV编码对病毒复制至关重要的丝氨酸蛋白酶，目前市场上很少有蛋白酶抑制剂。在本文中，我们描述了基于异山梨醇的新型拟肽抑制剂的合成和筛选，其中化合物1d，1e和1i在100 µM的体外对蛋白酶的活性具有明显的抑制作用。化合物1e也显示出剂量反应（IC 50 （= 36±3 µM）并以100 µM抑制蛋白酶突变体D168A和V170A，表明它是有希望的HCV NS3 / 4A蛋白酶抑制剂。我们的分子模型研究表明，1e的活性与S2和S4子位点相互作用的变化有关，因为增加的柔韧性有助于降低对D168A的活性，而S4子位点中疏水腔的出现增加了D1A的活性。抑制V170A毒株。

  A facile and effective approach for the synthesis of 4-arylidene-2-phenyl-5(4H)-oxazolones has been developed. Under solvent-assisted grinding in the presence of 2,4,6-trichloro-1,3,5-triazine, catalytic triphenylphosphine, and sodium carbonate, dehydration–condensation of hippuric acid with aromatic aldehydes proceeded rapidly within minutes at room temperature to afford the products in good to excellent

  We describe a palladium-catalyzed diastereo- and enantioselective formal [3 + 2]-cycloaddition between substituted vinylcyclopropanes and electron-deficient olefins in the form of azlactone- and Meldrum's acid alkylidenes to give highly substituted cyclopentane products. By modulation of the electronic properties of the vinylcyclopropane and the electron-deficient olefin, high levels of stereoselectivity

  我们描述了钯催化的非对映选择性和对映选择性形式的 [3 + 2]-环加成反应，在取代的乙烯基环丙烷和缺电子烯烃之间以 azlactone-和 Meldrum 的酸亚烷基的形式发生，得到高度取代的环戊烷产品。通过调节乙烯基环丙烷和缺电子烯烃的电子特性，获得了高水平的立体选择性。由催化剂提供的远程立体诱导，远离由配体产生的手性口袋，被认为是调用 Curtin-Hammett 原理的新机制的结果。

  Hepatitis C (HCV) infection is a cause of chronic liver disease such as cirrhosis, carcinoma, or liver failure, and the current therapy is effective in only 50% of patients. Serine proteases, which are present in HCV, are the most studied class of proteolytic enzymes­, and are a primary target in the drug development field. In this paper, we describe the synthesis and biological studies of a novel­ class of peptide mimetic compounds as potential HCV serine protease inhibitors.

  丙型肝炎病毒感染是导致肝硬化、肝癌或肝功能衰竭等慢性肝病的原因之一，而目前的治疗方法仅对50%的患者有效。HCV中的丝氨酸蛋白酶是最受研究的蛋白酶类别，也是药物开发领域的主要靶点。本文描述了一类新型肽模拟化合物作为潜在HCV丝氨酸蛋白酶抑制剂的合成和生物学研究。
