  • Catalyst-Controlled Stereoselective <i>O</i>-Glycosylation: Pd(0) vs Pd(II)
    作者:Hui Yao、Shasha Zhang、Wei-Lin Leng、Min-Li Leow、Shaohua Xiang、Jingxi He、Hongze Liao、Kim Le Mai Hoang、Xue-Wei Liu
    DOI:10.1021/acscatal.7b01630
    日期:2017.8.4
    Stereoselective construction of various O-glycosidic bonds was first achieved by different palladium sources using 3,4-O-carbonate galactal as the donor to reach yields up to 95% under mild conditions. With Pd(II) catalyst coordination of this glycal donor from the β-face directed by carbonate group, hard nucleophiles (aliphatic alcohols) gave β-glycosides and α-glycosides were obtained from soft nucleophiles
    各种O-糖苷键的立体选择性构建首先是通过使用3,4- O-碳酸半乳糖作为供体,通过不同的钯源实现的,在温和的条件下,收率可达95%。用Pd(II)催化剂从由碳酸酯基团定向的β面配位该糖基供体,硬的亲核试剂(脂族醇)得到β-糖苷,而α-糖苷则从软的亲核试剂(苯酚)制得。相比之下,由于空间效应,Pd(0)催化剂从β面上配位给体,硬受体和软受体都只能通过氢键介导的糖苷配基生成β-糖苷。
  • Unprecedented stability of δ-lactones with axial substituents rather than equatorial ones; comparison with the Prelog–Djerassi lactone derivative
    作者:Yoshiki Morimoto、Atsushi Mikami、Haruhisa Shirahama
    DOI:10.1039/c39910001376
    日期:——
    A 1 : 1 mixture of the trisubstituted δ-lactones 11a and 11b was subjected to thermodynamically equilibrated conditions to give predominantly 11b with axial substituents rather than 11a with all equatorial ones, in contrast to the Prelog–Djerassi lactone derivatives 3a and 3b, and, further surprisingly, it has been found that the disubstituted lactone 10 also adopts a chair conformation with axial substituents.
    在热力学平衡条件下,三取代δ-内酯 11a 和 11b 的 1 : 1 混合物主要产生具有轴向取代基的 11b,而不是全部具有赤道取代基的 11a,这与 PrelogâDjerassi 内酯衍生物 3a 和 3b 形成鲜明对比。
  • Steric constraints against [3,3]-sigmatropic rearrangement of allylic azides. A convenient approach to β-l-4-aminopent-2-enoglyceropyranosides
    作者:Cristiana Fava、Roberta Galeazzi、Giovanna Mobbili、Mario Orena
    DOI:10.1016/s0957-4166(01)00450-5
    日期:2001.10
    Starting from alkyl alpha -D-4-O-methanesulphonylpent-2-enoglyceropyranosides 13a-c, nucleophilic substitution carried out with polymer-supported azide ion led to regioisomeric mixtures of the azides 14a-c and 15a-c. An analogous result, due to a [3,3]-sigmatropic rearrangement, was observed starting from methyl alpha -D-hex-2-enoerythropyranoside derivatives 6a and 6b. On the contrary, starting from alkyl beta -D-4-O-methanesulphonylpent-2-enoglyceropyranosides 21a-c, azides 22a-c were exclusively obtained. and subsequently converted into the corresponding amino derivatives 23a-c. The behaviour of P-anomers 21a-c was ascribed to steric interactions in the cyclic transition state, as supported by ab initio calculations. (C) 2001 Elsevier Science Ltd. All rights reserved.
  • Iodine(V) Reagents in Organic Synthesis. Part 3. New Routes to Heterocyclic Compounds via <i>o</i>-Iodoxybenzoic Acid-Mediated Cyclizations:  Generality, Scope, and Mechanism
    作者:K. C. Nicolaou、P. S. Baran、Y.-L. Zhong、S. Barluenga、K. W. Hunt、R. Kranich、J. A. Vega
    DOI:10.1021/ja012126h
    日期:2002.3.1
    The discovery and development of the o-iodoxybenzoic acid (IBX) reaction with certain unsaturated N-aryl amides (anilides) to form heterocycles are described. The application of the method to the synthesis of delta-lactams, cyclic urethanes, hydroxy amines, and amino sugars among other important building blocks and intermediates is detailed. In addition to the generality and scope of this cyclization
    描述了邻碘氧基苯甲酸 (IBX) 与某些不饱和 N-芳基酰胺(苯胺)反应形成杂环的发现和发展。详细介绍了该方法在 δ-内酰胺、环氨基甲酸酯、羟基胺和氨基糖等重要结构单元和中间体的合成中的应用。除了这种环化反应的一般性和范围外,本文还描述了许多机理研究,表明单电子从苯胺官能团转移到 IBX,并暗示了该反应的基于自由基的机制。
  • Unexpected stability of δ-lactones with axial substituents rather than equatorial ones. Conformational evaluation by molecular mechanics and molecular orbital calculations
    作者:Yoshiki Morimoto、Haruhisa Shirahama
    DOI:10.1016/s0040-4020(96)01138-6
    日期:1997.2
    trisubstituted δ-lactones 5a and 5b was subjected to thermodynamically equilibrated conditions to give predominantly 5b with axial substituents rather than 5a with all equatorial ones, in contrast to the Prelog-Djerassi lactone derivatives 3a and 3b. Further surprisingly, it has been found that the disubstituted lactone 15 also adopts a half-chair conformation with axial substituents. The conformational analyses
    与Prelog-Djerassi内酯衍生物3a和3b相反,将三取代的δ-内酯5a和5b的1:1混合物置于热力学平衡的条件下,主要得到具有轴向取代基的5b而不是所有赤道取代基5a。进一步令人惊奇地发现,二取代的内酯15也采用带有轴向取代基的半椅构型。通过分子力学和分子轨道计算对这些化合物进行的构象分析强调了网状效应和静电相互作用,这是偏向于轴向构象异构体的原因。
