  • Iridium-Catalyzed Dynamic Kinetic Isomerization: Expedient Synthesis of Carbohydrates from Achmatowicz Rearrangement Products
    作者:Hao-Yuan Wang、Ka Yang、Scott R. Bennett、Sheng-rong Guo、Weiping Tang
    DOI:10.1002/anie.201503151
    日期:2015.7.20
    A highly stereoselective dynamic kinetic isomerization of Achmatowicz rearrangement products was discovered. This new internal redox isomerization provided ready access to key intermediates for the enantio‐ and diastereoselective synthesis of a series of naturally occurring sugars. The nature of the de novo synthesis also enables the preparation of both enantiomers.
    发现了Achmatowicz重排产物的高度立体选择性的动态动力学异构化。这种新的内部氧化还原异构化为一系列天然糖的对映和非对映选择性合成提供了关键中间体的现成通道。从头合成的性质还使得能够制备两种对映异构体。
  • A Divergent Synthesis of Uncommon Sugars from Furanaldehyde

    A practical synthetic strategy has been developed for producing uncommon sugars. This method employed kinetic enzymatic resolution of 1-(2-furyl)ethanol, and followed by NBS-mediated Achmatowicz rearrangement to construct α,β-unsaturated lactones. After further derivatization, five representative uncommon sugar units were successfully synthesized.
    已经开发出一种实用的合成策略来生产稀有糖。该方法采用1-(2-呋喃基)乙醇的动力学酶解法,接着通过NBS介导的Achmatowicz重排构建α,β-不饱和内酯。经过进一步衍生化,成功合成了五个代表性的稀有糖单元。
  • Stereoselective Synthesis of the Naturally Occurring Lactones (−)-Osmundalactone and (−)-Muricatacine Using Ring-Closing Metathesis
    作者:Miguel Carda、Santiago Rodríguez、Florenci González、Encarnación Castillo、Alicia Villanueva、J. Alberto Marco
    DOI:10.1002/1099-0690(200208)2002:15<2649::aid-ejoc2649>3.0.co;2-t
    日期:2002.8
    The stereoselective synthesis of the naturally occurring lactones osmundalactone (−)-1 and muricatacin (−)-2 is described. The key steps in each synthesis are the stereoselective addition of a Grignard reagent to a suitably protected α-hydroxy aldehyde and a ring-closing metathesis.
