  • Synthesis of bicyclic γ-butyrolactone derivatives by rhodium catalyzed intramolecular C–H insertion of α-dizao α-phosphoryl cycloalkyl esters
    作者:Jr-Yun Shie、Jia-Liang Zhu

    日期:2016.3
    products can be further elaborated into α,α-dialkyl γ-butyrolactones via a two-step alkylation/reductive alkylation sequence with the controlled installation of two alkyl groups to the lactones. In addition, application of Horner–Wadsworth–Emmons (HWE) olefination reaction to the insertion products allows an access to bicyclic α-alkylidene-γ-butyrolactone ring systems that occur ubiquitously in biologically
    在Rh 2(OAc)4的催化下,几种容易制备的环烷基α-重氮α-磷酸酯经过分子内C–H插入反应,以不同的收率(10%–80%)和dr比率(69:14: 17至> 99:1)。实验结果表明,前体的反应性和环化的非对映选择性都受环烷基部分的环大小的影响。而且,大多数得到的产物可以通过两步烷基化/还原烷基化序列在受控地将两个烷基安装到内酯上而进一步加工成α,α-二烷基γ-丁内酯。此外,

    日期:1998.9
    α-Methylene-γ-lactone fused to cycloheptane ring was synthesized by intramolecular cyclization of 8-(ethoxycarbonyl)- or 8-(acetoxymethyl)-9-(trimethylsilyl)non-7-enoyl chloride followed by lactonization. α-Methylene-γ-lactone fused to cyclooctane and cyclotetradecane ring were also synthesized from 9-(acetoxymethyl)-10-(trimethylsilyl)dec-8-enoyl chloride and 15-(acetoxymethyl)-16-(trimethylsilyl)hexadec-14-enoyl

    DOI:10.1246/bcsj.74.1947
    日期:2001.10
    α-Methylene γ -lactone fused to seven-membered carbocycle was synthesized by intramolecular cyclization of (2-ethoxycarbonylallyl)trimethylsilane or (2-acetoxymethylallyl)trimethylsilane with acid chloride. The former was found to be a better way for seven-membered carbocyclization, while the latter method was applicable to the synthesis of α- methylene γ -lactones fused to eight- and fourteen-membered carbocycles
