    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).

    由烯丙酸酯通过炔基烯酸酯中间体合成官能化的α,α-二取代的β-炔基酯。
    摘要:
    高取代度的α,α-二取代的β-炔基酯很容易由烯丙基酯和由酰胺碱介导的烷基卤,酰氯或氯甲酸烷基酯制备。这种高效温和的方法可耐受各种官能团,并以良好或极好的收率提供α,α-二取代的β-炔基酯。该方法特别适合于合成1,n-烯炔或1,n-二炔(n> 4)。1,5-烯炔的亲电环化产生高度官能化的γ-碘内酯,而其铂催化的环异构化产生1,3-环己二烯。

  • Synthesis of Functionalized α,α-Disubstituted β-Alkynyl Esters from Allenoates through an Alkynylenolate Intermediate
    作者:Weibo Wang、Bo Xu、Gerald B. Hammond
    DOI:10.1021/ol801287t
    日期:2008.9.1
    Highly substituted alpha,alpha-disubstituted beta-alkynyl esters are readily prepared from allenyl esters and either alkyl halide, acid chloride, or alkyl chloroformate, mediated by an amide base. This highly efficient and mild process tolerates various functional groups and provides alpha,alpha-disubstituted beta-alkynyl esters in good to excellent yields. This method is especially suitable for the

  • Michael Addition of Allenoates to Electron-Deficient Olefins: Facile Synthesis of 2-Alkynyl-Substituted Glutaric Acid Derivatives
    作者:Le-Ping Liu、Bo Xu、Gerald B. Hammond
    DOI:10.1021/ol801411b
    日期:2008.9.1
    A Michael addition of allenoates to electron-deficient olefins was mediated efficiently by a catalytic amount of commercial tetra-n-butylammonium fluoride (TBAF) under mild conditions. And 2-alkynyl substituted glutaric acid derivatives, which may be potential building blocks in organic synthesis, were obtained in good to excellent yields from these reactions. The mechanism for the Michael addition
