  • Diastereoselectivity in the Synthesis of Unnatural α-Amino Acid Esters by Phase Transfer Catalysis
    作者:Francisco Furtado Tavares Lins、Lázaro Pereira da Cunha、Yvone Brígido Memória Pouliquen、Telma Leda Gomes Lemos、Marcos Carlos de Mattos
    DOI:10.1515/znb-2004-0312
    日期:2004.3.1

    Two unnatural α-amino acid esters were prepared in good yields via phase transfer catalyzed Michael addition of ethyl N-acetylaminocyanoacetate to chalcone and benzalketone. For both α- enones, a progressive increase in product diastereomeric excess (d.e.) was observed during the course of reaction, even in the absence of quaternary ammonium salt. However, for a fixed reaction time, higher d.e. values were obtained under phase transfer catalytic condition. Analogous reactions were performed using S-aryl thiocinnamates as Michael acceptors, affording a 2-pyrrolidinone in good yield but low d.e. These results were interpreted on the basis of the reversibility of the Michael reaction

    通过相转移催化的Michael加成反应,乙酰氨基氰乙酸乙酯与查尔酮和苯基酮反应,制备了两种非天然的α-氨基酸酯,产率良好。对于两种α-烯酮,即使在没有季铵盐的情况下,反应过程中观察到产物对映异构体过量(d.e.)的逐渐增加。然而,在相转移催化条件下,对于固定的反应时间,获得了更高的d.e.值。使用S-芳基硫代肉桂酸酯作为Michael受体进行类似的反应,产率良好但d.e.较低,这些结果是基于Michael反应的可逆性进行解释的。
  • FeCl<sub>3</sub>-Promoted Intramolecular Annulation of δ-Keto Nitriles: Facile Approach to Prepare 3-Acetamido-2-pyridone Derivatives
    作者:Shaozhong Wang、Jia Pan、Yuefei Hu、Hongwen Hu
    DOI:10.1055/s-2005-861785
    日期:——
    A facile approach was developed to synthesize 3-acetamido-2-pyridone derivatives in moderate yields from δ-keto nitriles, derived from Michael addition between ethyl acetamidocyanoacetate and α,β-unsaturated ketones. The tandem reaction sequence promoted by FeCl3 involves intramolecular ketone-nitrile annulation followed by aromatization via selective decarbethoxylation. A plausible mechanism is also described.
    本研究开发了一种简便的方法,以δ-酮腈为原料合成 3-乙酰氨基-2-吡啶酮衍生物,产率适中,该衍生物来自乙酰氨基氰基乙酸乙酯与δ,δ-不饱和酮的迈克尔加成反应。在 FeCl3 的促进下,串联反应序列包括分子内酮腈环化,然后通过选择性脱甲氧基芳香化。此外,还描述了一种合理的机理。
  • A Novel Approach to 1,2-Dihydro-2-Oxo-3-Pyridinecarboxylic Ester via Aromatization Induced by Deamidation
    作者:Yuefei Hu、Gang Yu、Shaozhong Wang、Kai Wang、Hongwen Hu
    DOI:10.1055/s-2004-822325
    日期:——
    A novel approach was developed for the preparation of 4,6-disubstituted-1,2-dihydro-2-oxo-3-pyridinecarboxylic ester in moderate to good yields. This route involves a reaction sequence of Michael addition, transformation to ene-lactam, and aromatization, featuring easily available material, variable substituents, and good functional compatibility.
    开发了一种新方法用于制备4,6-二取代-1,2-二氢-2-氧-3-吡啶羧酸酯,产率中等到良好。该路线涉及迈克尔加成、转化为烯内酯和芳构化的反应序列,特点是使用的材料易得、取代基可变且功能兼容性良好。
