  Enantioselective inhibition of reverse transcriptase (RT) of HIV-1 by non-racemic indole-based trifluoropropanoates developed by asymmetric catalysis using recyclable organocatalysts

  摘要：

  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。

  cooperative catalysis model has been reported for the asymmetric Friedel–Crafts (F–C) alkylation of indoles with trifluoromethyl pyruvates using Trost’s intramolecular dinuclear zinc complex as the catalyst. This dinuclear zinc catalyst was prepared in situ by reacting the chiral ligand (S,S)-L2b with 2 equiv of ZnEt2. A series of trifluoromethyl alcohol and indole-containing biological compounds were formed

  据报道，使用Trost分子内双核锌络合物作为催化剂，吲哚与三氟甲基丙酮酸酯的不对称Friedel-Crafts（FC）烷基化的双金属协同催化模型。这种双核锌催化剂通过手性配体（反应原位制备S，S - ）L2b的与2当量ZnEt的2。在温和的条件下，在10 mol％的催化剂存在下，以中等至良好的收率（高达95％）和良好的对映选择性（高达88％对映体过量（ee））形成一系列三氟甲醇和含吲哚的生物化合物。提出了一种协同过渡状态模型来解释不对称感应的起源。

  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.

  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 coordinated OH group in cationic complexes [eta(n)-ring)M(NOH)(Solv)][SbF6] and [(eta(n)-ring)M(NOH)(R)-P1}][SbF6](2) ((eta(n)-ring)M = (eta(5)-C5Me5)Rh, (eta(5)-C5Me5)Ir, (eta(6)-p-MeC(6)H(4)iPr)Ru; NOH = hydroxypyridine ligand; (R)-P1 = (R)-monophos) is deprotonated by Na2CO3, rendering bi- or mononuclear compounds of formulas [(eta(n)-ring)M(kappa N-2,O-mu-O-NO}(2)][SbF6](2) and [(eta(n)-ring)M(NO)(R)-P1}][SbF6], respectively. The complexes have been characterized by analytical and spectroscopic means, including the determination of the crystal structures of [((eta(n)-ring)M(kappa N-2,O-mu-O-NO}(2)[SbF6](2) (NOH = NOH-1, (eta(n)-ring)M = (eta(5)-C5Me5)Rh, 8a; (eta(6)-p-MeC(6)H(4)iPr)Ru, 8c) and [(eta(5)-C5Me5)Ir(NO)-((R)-P1}][SbF6] (NOH = (R)-NOH-2; (R)-11b) by X-ray diffractometric methods. In complexes [(eta(n)-ring)M(NOH)(P*)1[SbF6](2) (P* = chiral phosphoramidite ligand) the proton of the coordinated hydroxypyridine ligand is able to activate the carbonyl group of methyl 3,3,3-trifluoropyruvate toward the Friedel-Crafts addition of indoles. In most cases, quantitative conversion is achieved in a few minutes, at -70 degrees C, with an ee of up to 8296. NMR data support the activation of the pyruvate by interaction between its carbonyl oxygen and the OH group of the coordinated hydroxymethylpyridine. Therefore, the metallic complexes act as Lewis acid assisted Bronsted acid catalysts.
