    Highly Regioselective Fluorination and Iodination of Alkynyl Enolates
    摘要:
    A simple yet efficient approach to various functionalized quaternary alpha-alkynyl alpha-fluoro esters and gamma-iodoallenoates from readily available allenoates through an alkynyl enolate intermediate generated by LDA is presented. Reaction of this alkynyl enolate with NFSI gives the alpha-product (alpha-alkynyl-alpha-fluoro ester), whereas the reaction of the silyl ether of alkynyl enolate with I-2 gives solely the gamma-product (iodoallenoate).

  • Ferric Chloride Hexahydrate-Catalyzed Highly Regio- and Stereoselective Conjugate Addition Reaction of 2,3-Allenoates with Grignard Reagents: An Efficient Synthesis of β,γ-Alkenoates
    作者:Guobi Chai、Zhan Lu、Chunling Fu、Shengming Ma
    DOI:10.1002/adsc.200900091
    日期:2009.8
    Ferric chloride hexahydrate was shown to be an efficient catalyst for the conjugate addition of 2,3-allenoates with alkyl-, aryl-, or vinyl-Grignard reagents to synthesize polysubstituted β,γ-unsaturated alkenoates with high regio- and stereoselectivity. The in situ formed magnesium dienolate may readily react with different electrophilic reagents under different reaction conditions with or without

    作者:Zhao Fang、Chunling Fu、Shengming Ma
    DOI:10.1002/ejoc.201001661
    日期:2011.3
    An operationally simple, TFA-promoted regioselective hydroarylation reaction of 2,3-allenoates with N-Ts- or N-Ac-indoles to afford 4-indolyl-4-arylbut-2-enoates is described. A series of substrates was tested, and the E/Z selectivity was found to depend on the reaction temperature and time. A mechanism involving the formation of E and Z allylic carbocations generated in situ from the reaction of 2
    描述了 2,3-alenoates 与 N-Ts-或 N-Ac-indoles 的操作简单、TFA 促进的区域选择性加氢芳基化反应,以提供 4-indoyl-4-arylbut-2-enoates。测试了一系列底物,发现 E/Z 选择性取决于反应温度和时间。提出了一种机制,该机制涉及由 2,3-烯丙酸与 TFA 反应原位生成的 E 和 Z 烯丙基碳正离子以及随后在吲哚的 3 位进行 Friedel-Crafts 攻击来解释结果。
