    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).

  • Manganese-Catalyzed C−H Annulation of Ketimines with Allenes: Stereoselective Synthesis of 1-Aminoindanes
    作者:Chong Lei、Lijie Peng、Ke Ding

    日期:2018.8.6
    A manganese‐catalyzed C−H annulation of ketimines with poly‐substituted ester‐activated allenes toward the synthesis of 1‐aminoindanes bearing two vicinal all‐substituted carbon stereocenters and an exocyclic double bond was developed. The reaction features high diastereoselectivity, high E/Z selectivity, 100% atom‐economy, broad substrate scope and good functional group tolerance.

    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

    A highly efficient gold(I) chloride catalyzed cycloisomerization of 2-alkynyl-1,5-diol (1) to dioxabicyclo[4.2.1] ketal (2) and its further transformation to tetrahydropyran (3) are reported. The diol is readily obtained by the reduction of 2-alkynyl-substituted glutarates, isolated from the Michael addition of allenoates to methyl acrylate.

    nucleophile attacks a gold-activated carbon-carbon multiple bond to give an alkenyl Au intermediate, notwithstanding the fact that these intermediates are hitherto unknown. We have obtained room temperature stable gamma-lactone gold(I) complexes through the reaction of cationic Au(I) reagents with allenoates, under mild conditions. The reactions of one such complex with electrophiles yielded the expected products
