  • Anhydrides as α,β-unsaturated acyl ammonium precursors: isothiourea-promoted catalytic asymmetric annulation processes
    作者:Emily R. T. Robinson、Charlene Fallan、Carmen Simal、Alexandra M. Z. Slawin、Andrew D. Smith
    DOI:10.1039/c3sc50199j
    日期:——
    The asymmetric annulation of a range of α,β-unsaturated acyl ammonium intermediates, formed from isothiourea HBTM 2.1 and anhydrides with either 1,3-dicarbonyls, β-ketoesters or azaaryl ketones gives either functionalised esters (upon ring opening), dihydropyranones or dihydropyridones in good yields (up to 93%) and high enantioselectivity (up to 97% ee).
    一系列α,β-不饱和酰胺铵中间体的不对称环化反应,这些中间体由异硫脲HBTM 2.1与酸酐(带有1,3-二羰基、β-酮酯或氮杂芳基酮)反应形成,可以高产率(高达93%)和高对映选择性(高达97% ee)得到功能化的酯(环打开后)、二氢吡喃酮或二氢吡啶酮。
  • Chiral N-heterocyclic carbene catalyzed annulation of α,β-unsaturated aldehydes with 1,3-dicarbonyls
    作者:Zhi-Qiang Zhu、Xing-Liang Zheng、Ning-Fei Jiang、Xiaolong Wan、Ji-Chang Xiao
    DOI:10.1039/c1cc12778k
    日期:——
    Chiral N-heterocyclic carbene catalyzed annulations of ynals and enals with 1,3-dicarbonyls have been described. The two reactions provided direct and efficient methods for enantioselective synthesis of functionalized dihydropyranones. Comparatively, the reactions starting from ynals were atom-economical; furthermore the reactions of enals demonstrated broader substrate compatibility.
    已经描述了手性N-杂环卡宾催化的具有1,3-二羰基的烯醛和烯醛的环。这两个反应为功能化二氢吡喃酮的对映选择性合成提供了直接和有效的方法。相比之下,从自醛开始的反应是原子经济的。此外,烯醛的反应证明了更广泛的底物相容性。
  • N-Heterocyclic Carbene-Catalyzed Enantioselective Annulation of Bromoenal and 1,3-Dicarbonyl Compounds
    作者:Fang-Gang Sun、Li-Hui Sun、Song Ye
    DOI:10.1002/adsc.201100622
    日期:2011.11
    Highly enantioselective [3+3] annulation reactions of bromoenals and 1,3-dicarbonyl compounds are reported. In addition, both enantiomers of the resultant dihydropyranone could be easily obtained by choosing N-heterocyclic carbenes (NHCs) with the same stereocenter but different substituents under the optimized reaction conditions.
    报道了溴烯和1,3-二羰基化合物的高度对映选择性[3 + 3]环化反应。另外,通过在优化的反应条件下选择具有相同立体中心但具有不同取代基的N-杂环卡宾(NHC),可以轻松获得所得二氢吡喃酮的两种对映体。
