  L-赤藓糖衍生物与手性α-氨基和α-氟醛之间的羟醛反应：Felkin-Anh和Cornforth过渡态之间的竞争。

  摘要：

  在受保护的L-赤藓糖衍生物的硼烯酸酯与几种手性α-氟和α-氨基醛的醛醇缩合反应中已经观察到匹配的和错配的非对映选择性。如先前在α-氧化醛的情况下所观察到的，对于各个过渡结构严格遵守Felkin-Anh模型并不能令人满意地解决所有观察到的结果。在某些情况下，只有Cornforth模型提供了很好的解释。讨论了影响该二分法的因素，并提出了用于与α-杂原子取代的醛的醛醇缩合反应的通用机理模型。该模型的其他支持是从密度泛函计算中获得的。

  1,2-氟代醇的不对称合成：铱催化氟化烯丙醇的氢化

  摘要：

  我们已经开发了一种简单的方案，可以使用有效的氮杂双环噻唑-膦铱络合物通过氟化烯丙基醇的不对称氢化来制备1,2-氟代醇。铱催化的手性1,2-氟代醇分子的不对称合成是在环境温度下以操作简便和可扩展性进行的。该方法与各种芳族，脂族和杂环氟化化合物以及多种多氟化化合物兼容，从而以优异的收率和对映选择性提供了相应的产物。

• Iridium Catalysts with Chiral Imidazole-Phosphine Ligands for Asymmetric Hydrogenation of Vinyl Fluorides and other Olefins

  New chiral bidentate imidazole-phosphine ligands have been prepared and evaluated for the iridium-catalysed asymmetric hydrogenation of olefins. The imidazole-phosphine-ligated iridium catalysts hydrogenated trisubstituted olefins with the same sense of enantiodiscrimination as known iridium catalysts possessing oxazole and thiazole as N-donors. The imidazole-based catalysts were shown to hydrogenate

• Oxidative Enantioselective α-Fluorination of Aliphatic Aldehydes Enabled by N-Heterocyclic Carbene Catalysis

  Described is the first study on oxidative enantioselective α‐fluorination of simple aliphatic aldehydes enabled by N‐heterocyclic carbene catalysis. N‐fluorobis(phenyl)sulfonimide serves as a an oxidant and as an “F” source. The CF bond formation occurs directly at the α position of simple aliphatic aldehydes, thus overcoming nontrivial challenges, such as competitive difluorination and nonfluorination

  The development of a general organocatalyst for the alpha-functionalization of aldehydes, via an enamine intermediate, is presented. Based on optically active alpha,alpha-diarylprolinol silyl ethers, the scope and applications of this catalyst for the stereogenic formation of C-C, C-N, C-F, C-Br, and C-S bonds are outlined. The reactions all proceed in good to high yields and with excellent enantioselectivities. Furthermore, we will present mechanistic insight into the reaction course applying nonlinear effect studies, kinetic resolution, and computational investigations leading to an understanding of the properties of the alpha,alpha-diarylprolinol silyl ether catalysts.
• Iridium-Catalyzed Asymmetric Hydrogenation of Fluorinated Olefins Using N,P-Ligands:  A Struggle with Hydrogenolysis and Selectivity

  To broaden the substrate scope of asymmetric iridium-catalyzed hydrogenation, fluorine-functionalized olefins were synthesized and hydrogenated with iridium complexes. Preliminary results showed high levels of fluorine elimination together with low selectivity. The loss of vinylic fluorine at first seemed difficult to handle, but further studies revealed that a catalyst with an azanorbornyl scaffold in the ligand gave more promising results. With this in mind, a new ligand was developed. This gave among the best results published to date for fluorine asymmetric hydrogenation, yielding high conversion and very high ee's with very little fluorine elimination. Further increasing the selectivity, the trials also revealed that tetrasubstituted fluorine-containing olefins can be hydrogenated with high ee's, despite that this class of compounds has usually shown low reactivity in this reaction type.

  Biocatalytic reduction of 2-fluorocinnamyl alcohols mediated by Saccharomyces cerevisiae was investigated in phosphate buffer solutions. Product analysis clearly showed that (S)-2-fluoro-3-arylpropanols were afforded in high yields with up to 92% ee Value. (C) 2010 Published by Elsevier Ltd.
