  摘要：

  The continued exploration of a series of 3-(arylmethyl)-1H-indole-5-carboxamides by the introduction of fluorinated amide substituents has resulted in the discovery of 4-[[5-[((2R)-2-methyl-4,4,4-trifluorobutyl)carbamoyl]-1-methylindol-3-yl]methyl]-3-methoxy-N-[(2-methylphenyl)sulfonyl]benzamide (38p, ZENECA ZD 3523),which has been chosen for clinical evaluation. This compound exhibited a K-i of 0.42 nM for displacement of [H-3]LTD(4) on guinea pig lung membranes, a pK(B) Of 10.13 +/- 0.14 versus LTE(4) on guinea pig trachea, and an oral ED(50) Of 1.14 mu mol/kg opposite LTD(4)-induced bronchoconstriction in guinea pigs. The R enantiomer was found to be modestly more potent than the S enantiomer 38o. Modification of the amide substituent to afford achiral compounds was unsuccessful in achieving comparable levels of activity. Profiling of 38p opposite a variety of functional assays has demonstrated the selectivity of this compound as a leukotriene receptor antagonist. The enantioselective synthesis of 38p, which employed a diastereoselective alkylation of (4R,5S)-3-(1-oxo-4,4,4-trifluorobutyl)-4-methyl-5-phenyl-2-oxazolidinone (27) as the key step to establish the chirality of the amide substituent, provided an efficient route for generating 38p in >99% enantiomeric purity.

  enables the direct conversion of both strong aliphatic and benzylic C-H bonds into the corresponding C(sp3)-CF3 products in a single step using a bench-stable, commercially available trifluoromethylation reagent. The reaction requires only a single equivalent of substrate and proceeds with excellent selectivity for positions distal to unprotected amines. To demonstrate the utility of this new methodology

  三氟甲基（CF3）基团的引入可以显着改善化合物的生物学特性。尽管三氟甲基化的化合物已确立的重要性，但是用于烷基CH键的三氟甲基化的通用方法仍然难以实现。在这里，我们报告通过光驱动，decatungstate催化的氢原子转移和铜催化的合并发展双重催化的C（sp3）-H三氟甲基化。这种金属光氧化还原方法可使用稳定的市售三氟甲基化试剂，一步就将强脂族和苄基CH键直接转化为相应的C（sp3）-CF3产品。该反应仅需要单当量的底物，并且对于未保护的胺远端的位置具有优异的选择性。为了证明这种新方法在后期功能化中的实用性，我们直接衍生了各种已获批准的药物和天然产品，以生成有价值的三氟甲基化类似物。初步的机械实验表明，在此过程中形成了“ Cu-CF3”物质，并且关键的C（sp3）-CF3键形成步骤涉及铜催化剂。
