  The potential of P,O‐iminosugar based ligands in the Ir‐catalyzed asymmetric hydrogenation of minimally functionalized olefins is presented. These new ligands were prepared from easily available carbohydrates (D‐mannose, D‐ribose and D‐arabinose). The stereochemical and polyfunctional diversity of carbohydrates allowed the modulation of the ligands, both from their electronic properties and the rigidity

  提出了基于P，O-亚氨基糖的配体在Ir催化的最小官能化烯烃的不对称加氢中的潜力。这些新的配体由容易获得的碳水化合物（D-甘露糖，D-核糖和D-阿拉伯糖）制备。碳水化合物的立体化学和多官能度多样性可从其电子特性和主链刚性两个方面对配体进行调节。在选定的三取代和二取代的底物进行氢化反应时，可以达到较高的对映选择性（ee高达99％）。

  isomerization of primary allylic alcohols to chiral aldehydes using iridium‐catalysts bearing P,N‐MaxPHOX ligands has been studied. These catalysts can be fine‐tuned as they present three different stereogenic centers to modulate both the reactivity and enantioselectivity of a family of different substrates. The experimental part is supported by a DFT study of the reaction mechanism, which provides new

  This work identifies a family of Ir/phosphite-sulfoximine catalysts that has been successfully used in the asymmetric hydrogenation of olefins with poorly coordinative or noncoordinative groups. In comparison with analogue Ir/phosphine-sulfoximine catalysts previously reported, the presence of a phosphite group extended the range of olefins than can be efficiently hydrogenated. High enantioselectivities

  这项工作确定了Ir /亚磷酸酯-亚砜亚胺催化剂系列，已成功用于配位或非配位基团较弱的烯烃的不对称加氢中。与先前报道的类似的Ir /膦-亚砜亚胺催化剂相比，亚磷酸酯基团的存在扩展了烯烃的范围，而无法有效地氢化。对于包含相关的弱配位基团的各种烯烃（例如α，β-不饱和烯酮，酯，内酯和内酰胺以及烯基硼酸酯），已经实现了与对等最佳化合物相当的高对映选择性。

  Ir‐phosphinomethyl‐oxazoline complexes have been identified as efficient, highly enantioselective catalysts for the asymmetric hydrogenation of 3,3‐disubstituted allylic alcohols and related homoallylic alcohols. In contrast to other N,P ligand complexes, which require weakly coordinating solvents, such as dichloromethane, these catalysts perform well in more ecofriendly THF or 2‐MeTHF. Their synthetic

  Ir-膦基甲基-恶唑啉络合物已被认为是高效的，高对映选择性的催化剂，可用于3,3-二取代的烯丙醇和相关的均烯丙醇的不对称加氢反应。与其他需要弱配位溶剂（例如二氯甲烷）的N，P配体配合物相比，这些催化剂在更环保的THF或2-MeTHF中表现良好。它们的合成潜力已通过四种比沙泊烷倍半萜的正式全合成得到证明。
• Iridium-Catalyzed Asymmetric Hydrogenation with Simple Cyclohexane-Based P/S Ligands: <i>In Situ</i> HP-NMR and DFT Calculations for the Characterization of Reaction Intermediates

  We report a reduced but structurally valuable phosphite/phosphinite-thioether ligand library for the Ir-hydrogenation of 40 minimally functionalized alkenes, including relevant examples with poorly coordinative groups. We found that enantiomeric excesses are mainly dependent on the substrate structure and on some ligand parameters (i.e., the type of thioether/phosphorus moieties and the configuration of the phosphite group), whereas the substituents of the biaryl phosphite moiety had little impact. By tuning the ligand parameters we were able to find highly selective catalysts for a range of substrates (ee's up to 99%). These phosphite/phosphinite-thioether ligands have a simple backbone and thus yield simple NMR spectra that reduce signal overlap and facilitate the identification of relevant intermediates. Therefore, by combining HP-NMR spectroscopy and theoretical studies, we were also able to identify the catalytically competent Ir-dihydride alkene species, which made it possible to explain the enantioselectivity obtained.
