    Highly diastereoselective synthesis of two analogues of dihydrosphingosine
    摘要:
    Diastereomeric analogues 8 and 9 of dihydrosphingosine 2 with a shortened alkyl chain were obtained with high diastereoselectivity via addition of n-hexyl magnesium bromide or dihexylzinc to a chiral aldehyde 3, respectively. These compounds are precursors of new potentially hydrosoluble analogues of glycosphingolipides. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.

    Synthesis of bis(7-octenyl)zinc via heterogeneous Ni catalysts
    摘要:
    Grignard, photochemical, or borane-mediated hydrozincation synthetic routes afford non-volatile olefin functionalized bis(alkyl)zincs such as bis(7-octenyl)zinc (1). These traditional methods present limitations in product isolation and process scale-up. A hydrozincation route to synthesize these types of bis(alkyl)zincs utilizing heterogeneous catalysis has been developed from screening commercially available Ni and Rh supported catalysts using diethylzinc and 1-hexene as the olefin substrate. The catalytic hydrozincation process is optimized with the Ni catalysts (at 0.3 wt% Ni) to improve the yield of 1 by removal of ethylene coproduct from the reaction mixture. Process scale-up to 10 g of product is demonstrated with the most active Ni catalyst identified, to afford 1 in moderate yield after facile separation from the catalyst by product filtration.

  • Reaction of Nitrogen‐Radicals with Organometallics Under Ni‐Catalysis: N‐Arylations and Amino‐Functionalization Cascades
    作者:Lucrezia Angelini、Jacob Davies、Marco Simonetti、Laia Malet Sanz、Nadeem S. Sheikh、Daniele Leonori

    the generation of nitrogen‐radicals by ground‐state single electron transfer with organyl–NiI species. Depending on the philicity of the Nradical, two types of processes have been developed. In the case of nucleophilic aminyl radicals direct N‐arylation with aryl organozinc, organoboron, and organosilicon reagents was achieved. In the case of electrophilic amidyl radicals, cascade processes involving
    在此,我们报告了一种通过有机基-Ni I物质的基态单电子转移产生自由基的策略。根据 N-自由基的亲和性,已经开发了两种类型的工艺。在亲核基自由基的情况下,可实现与芳基有机锌、有机和有机试剂的直接N-芳基化。对于亲电子酰胺基自由基,已经开发了涉及分子内环化,然后与芳基和烷基有机属反应的级联过程。N-环化-烷基化级联引入了一种新颖的逆向合成断开方法,用于组装取代的内酰胺吡咯烷,其潜力在四种毒液生物碱的简短全合成中得到了证明。
  • Electrophilic amination of organozinc reagents with acetone O-(2,4,6-trimethylphenylsulfonyl)oxime and O-methylhydroxylamine

    Reaction of diorganozincs and triorganozincates with acetone O-(2,4,6-trimethylphenylsulfonyl)oxime or O-methylhydroxylamine in the presence of CuCN provides a new one-flask method for electrophilic amination of organozinc reagents. Considering the lithium- or magnesium-to-zinc transmetallation, this method also extends the scope of electrophilic amination of organolithiums and Grignard reagents.

    日期:2018.5.14
    In analogy to the classical reaction of C−B bonds with peroxides, the first oxidative functionalization of aminoboranes through a 1,2‐N migration was realized. Readily available aliphatic nitro compounds are thereby transformed into N‐ and O‐functionalized hydroxylamines in a single synthetic operation. Addition of hazardous peroxides is avoided. Instead, the insertion of O2, as the terminal oxidant
    类似于C-B键与过化物的经典反应,通过1,2-N迁移实现了硼烷的第一个化功能化。易于获得的脂肪硝基化合物可通过一次合成操作转化为N和O功能化的羟胺。避免添加有害的过化物。相反,将O 2作为末端化剂插入Zn-C键可提供必要的过化物。反过来,所需的有机基团是通过的交换,由硝基向硼烷转化的有机硼酸酯副产物形成的。

    An efficient method for the generation of chiral N-acylpyridinium salts from various pyridines and a chiral acid chloride promoted by means of silyl triflates as additives is presented. The stereoselective addition of organometallic reagents to the intermediate chiral N-acylpyridinium ions led to α-substituted N-acyldihydropyridines and N-acyldihydropyridones in good yields, whereas no or minor amounts
