  Herein, we report the development of efficient inhibitors of reverse transcriptase (RT) of HIV-1 based on indole-alkyl trifluoropyruvate derivatives by a TZM-bl cell assay. The inhibitory activities of the two enantiomers and the corresponding racemic mixture have been compared. TZM-bl cells exhibited strong enantioselective discrimination for the (R)-configuration, among these indole derivatives, the most active compound R-12, with a 5-NO2 substituent, gave the best result when tested in the TZM-bl cells on HIV virus type HIV-1IIIB, with an EC50 value of 0.019 μM, CC50 value of 210.697 μM and SI (selectivity index, CC50/EC50) value of 11 089, respectively. The cell test showed that, in most cases, the R-enantiomer was superior to the Rac-mixture, which was better than the corresponding S-enantiomer. The results indicated that the R-enantiomer is the most favorable configuration as an efficient HIV-1 inhibitor. Molecular modeling studies suggested a structural basis for the enantioselectivity of RT towards this class of molecules.

  在此，我们报道了基于吲哚-烷基三氟丙酮酸衍生物的高效HIV-1逆转录酶（RT）抑制剂的开发，通过TZM-bl细胞 assay进行。已经比较了两种对映体及其相应的消旋混合物的抑制活性。TZM-bl细胞对这些吲哚衍生物中的(R)-构型表现出强烈的立体选择性辨别。在这些吲哚衍生物中，活性最强的化合物R-12，带有一个5-NO2取代基，在TZM-bl细胞中对HIV病毒类型HIV-1IIIB进行测试时，得到了最好的结果，其EC50值为0.019 μM，CC50值为210.697 μM，SI（选择性指数，CC50/EC50）值为11089。细胞测试表明，在大多数情况下，R-对映体优于消旋混合物，后者又优于相应的S-对映体。结果表明，R-对映体是最有利于作为高效HIV-1抑制剂的构型。分子建模研究为RT对这类分子的立体选择性提供了结构基础。

  A mild and efficient catalyst system for asymmetric Friedel-Crafts alkylation of indoles with trifluoropyruvates was reported. The chiral ligands took the advantages of both the proline and the binaphthyl moieties, and the in situ prepared Cu(II) catalyst showed good substrate tolerance in the reactions. Indoles bearing different substituents could be tolerated, and the desired products could be obtained

  The highly enantioselective Friedel-Crafts reaction of indoles with trifluoropyruvate catalyzed by a C-3-symmetric cinchonine-squaramide is reported. A wide variety of trifluoromethylated indole derivatives were obtained in high yields and with excellent enantioselectivities (99% and up to > 99% ee). Moreover the C-3 catalyst can be easily recovered and was used five times. (C) 2012 Elsevier Ltd. All rights reserved.

  Indoles, and pyrroles, and furans, oh my! Chiral phosphoric acid catalyzed Friedel–Crafts alkylation of indoles with 3,3,3‐trifluoropyruvate gave the corresponding adducts in excellent yields with high enantioselectivities. Electron‐deficient indoles, in particular, exhibited excellent enantioselectivities.
