  Highly Enantioselective Chlorination of β-Keto Esters and Subsequent S_N2 Displacement of Tertiary Chlorides: A Flexible Method for the Construction of Quaternary Stereogenic Centers

  摘要：

  Highly enantioselective chlorination of beta-oxo esters and subsequent stereospecific substitution of tertiary chlorides are described. Enantioselective chlorination of beta-keto esters and malonates was performed using a chiral Lewis acid catalyst prepared from Cu(OTf)(2) and the newly developed spirooxazoline ligand 2 to yield the desired a-chlorinated products with high enantioselectivity (up to 98% ee). Nucleophilic substitution of the resulting chlorides proceeded smoothly to afford a variety of chiral molecules such as alpha-amino, alpha-allcylthio, and alpha-fluoro esters, without loss of enantiopurity. The results of X-ray crystallographic analysis proved that Walden inversion occurs at the chlorinated tertiary carbon center. These results supported the fact that the substitution proceeds via an S(N)2 mechanism.

• Chemo‐ and Enantioselective Oxidative α‐Azidation of Carbonyl Compounds

  We report high‐performance I+/H2O2 catalysis for the oxidative or decarboxylative oxidative α‐azidation of carbonyl compounds by using sodium azide under biphasic neutral phase‐transfer conditions. To induce higher reactivity especially for the α‐azidation of 1,3‐dicarbonyl compounds, we designed a structurally compact isoindoline‐derived quaternary ammonium iodide catalyst bearing electron‐withdrawing

  我们报告了在双相中性相转移条件下使用叠氮化钠对羰基化合物进行氧化或脱羧氧化α-叠氮化的高性能I + / H 2 O 2催化。为了诱导更高的反应活性，尤其是对于1,3-二羰基化合物的α-叠氮化，我们设计了结构紧凑的异吲哚啉衍生的带有吸电子基团的季碘化铵催化剂。I + / H 2 O 2的非生产性分解途径催化量可以通过使用催化量的自由基捕获剂来抑制。这种氧化偶合耐受各种官能团，可以很容易地应用于结构多样的复杂分子的后期α-叠氮化。此外，我们实现了1,3-二羰基化合物的对映选择性α-叠氮化，这是手性次碘酸盐催化剂与对映选择性分子间氧化偶联的第一个成功实例。
• Azidation of β-Keto Esters and Silyl Enol Ethers with a Benziodoxole Reagent

  日期：2013.7.5

  The efficient azidation of β-keto esters and silyl enol ethers using a benziodoxole-derived azide transfer reagent is reported. The azidation of cyclic β-keto esters could be achieved in up to quantitative yields in the absence of any catalyst. In the case of less reactive linear β-keto esters and silyl enol ethers, complete conversion and good yields could be obtained by using a zinc catalyst.

  据报道，使用苯并恶二唑衍生的叠氮化物转移试剂可有效地叠氮化β-酮酯和甲硅烷基烯醇醚。在不存在任何催化剂的情况下，可以高达定量的产率实现环状β-酮酯的叠氮化。在反应性较低的线性β-酮酯和甲硅烷基烯醇醚的情况下，通过使用锌催化剂可以获得完全的转化和良好的产率。

  The first example of Fe-catalyzed enantioselective azidations of β-keto esters and oxindoles using a readily available N3-transfer reagent is reported. A number of α-azido-β-keto esters were obtained with up to 93% ee, and this methodology also generates 3-substitued 3-azidooxindoles with high enantioselectivities (up to 94%).

  Detailed investigations concerning the organocatalytic (asymmetric) α-azidation of prochiral β-ketoesters were carried out. It was shown that the racemic version of such a reaction can either be carried out under oxidative conditions using TMSN₃ as the azide-source with quaternary ammonium iodides as the catalysts, or by using hypervalent iodine-based electrophilic azide-transfer reagents with different

  进行了有关前手性β-酮酸酯的有机催化（不对称）α-叠氮化的详细研究。已经表明，这种反应的外消旋形式可以在氧化条件下，以TMSN 3为叠氮化物源，以碘化季铵为催化剂，或通过使用基于高价碘的亲电子叠氮化物转移试剂与不同的有机催化剂进行。另外，当使用简单的金鸡纳生物碱催化剂时，尽管产率相对较低，但是后一种策略也可以以适度的对映选择性进行。
