  • Diastereoselective synthesis of α-(aminomethyl)-γ-butyrolactones via a catalyst-free aminolactonization
    作者:P. Veeraraghavan Ramachandran、Daniel R. Nicponski
    DOI:10.1039/c4cc05765a
    日期:——

    An auto-catalytic domino reaction involving an aza-Michael reaction, proton transfer, and lactonization furnishing α-aminomethyl-γ-butyrolactones in near quantitative yields and excellent diastereoselectivity is described.

  • 4-(Dimethylamino)pyridine as a catalyst for the lactonization of 4-hydroxy-2-methylenebutanoate esters
    作者:Daniel R. Nicponski
    DOI:10.1016/j.tetlet.2014.02.024
    日期:2014.3
    The catalytic action of 4-(dimethylamino)pyridine (DMAP) in lactonizing 4-hydroxy-2-methylenebutanoate esters to 2-methylene-γ-butyrolactones is described. The use of DMAP, which functions as an excellent complement to the more traditional acid-catalyzed lactonization protocol, allows for the synthesis of 2-methylene-γ-butyrolactones containing acid-sensitive groups under essentially neutral conditions
    描述了4-(二甲基基)吡啶DMAP)在将4-羟基-2-亚甲基丁酸酯酯化为2-亚甲基-γ-丁内酯中的催化作用。DMAP的使用可作为对更传统的酸催化内酯化方法的出色补充,可以在基本上中性的条件下合成含有酸敏感基团的2-亚甲基-γ-丁内酯
  • Synthesis of Functionalized Cyclopropanes from Carboxylic Acids by a Radical Addition–Polar Cyclization Cascade
    作者:Chao Shu、Riccardo S. Mega、Björn J. Andreassen、Adam Noble、Varinder K. Aggarwal
    DOI:10.1002/anie.201808598
    日期:2018.11.19
    Herein, we describe the development of a photoredox‐catalyzed decarboxylative radical addition–polar cyclization cascade approach to functionalized cyclopropanes. Reductive termination of radical–polar crossover reactions between aliphatic carboxylic acids and electron‐deficient alkenes yielded carbanion intermediates that were intercepted in intramolecular alkylations with alkyl chlorides appended
    在此,我们描述了光氧化还原催化的脱羧自由基加成-极性环化级联方法对功能化环丙烷的开发。脂肪族羧酸和缺电子烯烃之间的自由基-极性交叉反应的还原终止产生了碳负离子中间体,该碳负离子中间体在分子内烷基化中被附加到烯烃底物上的烷基拦截。温和的条件利用了现成的有机光催化剂和可见光,被证明适用于多种结构复杂的羧酸和多种烷基烯烃,表现出出色的官能团耐受性。
  • Intramolecular [3+2] cycloadditions of non-stabilised azomethine imidate-methylides

    DOI:10.1016/s0040-4039(00)99384-5
    日期:1989.1
    Non-stabilised azomethine imidate and thioimidate-methylides, generated via fluoride ion induced desilylation of N-(trimethylsilyl)methyl-2-alkoxy imminium salts undergo facile intramolecular cycloaddition with unactivated and electron deficient dipolarophiles affording pyrrolo-[2,3-b] furans and pyrans.
