• B(C₆ F₅ )₃ -Catalyzed Reduction of Cyclic <i>N</i> -Sulfonyl Ketimines

  日期：2019.10.17

  A metal‐free method for reduction of cyclic N‐sulfonyl ketimines catalyzed by B(C6F5)3, using commercially available methylphenylsilane as a reducing reagent under mild conditions has been developed. This reductive method was effective, not only providing the expected cyclic N‐Sulfonamides in good to excellent yields, but also showing good functional‐group tolerance.

  开发了一种无金属的方法，在温和的条件下，使用市售的甲基苯基硅烷作为还原剂，还原由B（C 6 F 5）3催化的环状N-磺酰基酮亚胺。这种还原方法是有效的，不仅可以提供预期的环状N-磺酰胺类化合物，而且产率很高，而且显示出良好的官能团耐受性。

  日期：2009.8.7

  Using pd(cf3co2)2/(S,S)-f-Binaphane as the catalyst, an efficient enantioselective synthesis of sultams was developed via asymmetric hydrogenation of the corresponding cyclic imines with high enantioselectivities. The hydrogenation products can be conveniently transformed to chiral homoallylic amines without loss of enantioselectivity.

  以pd（cf 3 co 2）2 /（S，S）-f-Binaphane为催化剂，通过高对映选择性的相应环状亚胺的不对称加氢反应，开发了有效的对映异构体。氢化产物可以方便地转化为手性均烯丙基胺，而不会损失对映选择性。

  carbene iridium complex featuring metal-centered chirality was designed and applied to the asymmetric transfer hydrogenation (ATH) of imines. Four strongly σ-donating carbon-based substituents (2 carbenes and 2 phenyl moieties), a chirality transfer directly from the stereogenic metal center to the C=N bond of substrates, as well as a restriction of catalyst deactivation by steric demanding substituents

  设计了具有金属中心手性的环金属化N-杂环卡宾铱配合物，并将其应用于亚胺的不对称转移氢化（ATH）。四个强σ供电的碳基取代基（2个碳烯和2个苯基部分），手性直接从立体金属中心转移至底物的C = N键，以及由于空间要求的取代基限制了催化剂的失活就催化剂的负载量（低至0.01 mol％），底物范围（24个实例）和对映选择性（94-98％ee）而言，这种新型的络合物是用于环N-磺酰亚胺的ATH的最有效的催化剂之一。

  Asymmetric reductive (hetero)arylations of imines using aryl and heteroaryl halides have been uncovered with a chiral cobalt-bisphosphine catalyst. This approach complements the traditional strategy using preformed organometallic reagents, and it exhibits good functional group compatibility under mild conditions.

  使用手性钴-双膦催化剂发现了使用芳基和杂芳基卤化物的亚胺不对称还原（杂）芳基化。这种方法补充了使用预制有机金属试剂的传统策略，并且在温和条件下表现出良好的官能团相容性。
• Iodotrimethylsilane and Catalytic Iodine Promoted Cyclization for the Facile Synthesis of 3-Monoarylated Five-Membered Benzosultams

  DOI：10.3987/com-09-11884

  日期：——

  3-Monoarylated five-membered benzosultams with various functional groups were prepared by simple and convenient two-step procedures. N-t-Bu-benzenesulfonamides were lithiated and reacted with substituted aromatic aldehydes to form the corresponding carbinols, which were converted to the cyclic compounds via a sequence of consecutive processes mediated by TMSCl-NaI-MeCN reagent and catalytic amount of iodine. Iodine played a crucial role in the eliminating the reductive side reaction in the cyclization processes.
