  • Intramolecular Sulfur Transfer in <i>N</i><i>-</i>Enoyl Oxazolidine-2-thiones Promoted by Brønsted Acids. Practical Asymmetric Synthesis of β-Mercapto Carboxylic Acids and Mechanistic Insights

    usually above 95:5. The relative efficiency of a range of acids (trifluoroacetic, difluoroacetic, acetic, triflic) is assessed showing TFA and TfOH as the most efficient and acetic acid as a totally inefficient reaction promoter. The new procedure complements the Lewis acid promoted reaction previously described by our group in two aspects: First, stereodivergent results are obtained for the Lewis acid
    证明了单独使用布朗斯台德酸有效促进 N-烯酰基恶唑烷-2-硫酮中的硫转移过程以产生 β-巯基羰基衍生物的能力。该反应对一系列烷基取代的 N-烯酰基恶唑烷-2-硫酮(dr 通常高于 98:2)进行了基本上完美的非对映控制,并且对大多数芳基取代的对应物(dr 通常高于 92:8)具有高选择性。重要的是,该反应在 β,β-二取代的 N-烯酰基恶唑烷-2-硫酮中也非常有效,产生选择性通常高于 95:5 的四元 CS 立体中心。评估了一系列酸(三氟乙酸、二氟乙酸、乙酸、三氟甲磺酸)的相对效率,显示 TFA 和 TfOH 是最有效的,而乙酸则是完全低效的反应促进剂。新程序在两个方面补充了我们小组先前描述的路易斯酸促进反应:首先,对路易斯酸或布朗斯台德酸促进的β,β-二取代烯酰基化合物的反应获得了立体发散结果。其次,虽然布朗斯台德酸促进的反应是立体有择的,在底物 E/Z 构型和产物立体化学之间提供了良好的相关性,但由路易斯酸

    日期:2011.8
    synthesis of optically active trifluoromethyl dihydropyranones and spirocyclic oxindole-dihydropyranones has been realized by the chiral N-heterocyclic carbenes-catalyzed cyclization of α,β-unsaturated β-methylacyl chlorides with activated trifluoromethyl ketones or isatin derivatives.

    日期:2013.1.7
    Cinchona alkaloids were used as Lewis base catalysts in the title reaction. The [4+2] cyclization of α,β‐unsaturated acyl chlorides with electron‐deficient alkenes derived from oxindole gave the corresponding spirocarbocyclic oxindoles.

    alkaloid-catalyzed [4 + 2] cyclocondensation of α,β-unsaturated acyl chlorides with imines is developed to give the corresponding substituted dihydropyridinones in good yields with high to excellent enantioselectivities. Reduction of the dihydropyridinones gave highly optically active substituted tetrahydropyridinone and piperidine derivatives.

  • <i>N</i>-Heterocyclic Carbene-Catalyzed All Carbon-[4+2] Cyclocondensation of<i>α</i>,<i>β</i>-Unsaturated Acyl Chlorides with 3-Alkylenyloxindoles
    作者:Litao Shen、Wenqiang Jia、Song Ye
    DOI:10.1002/cjoc.201400411
    日期:2014.8
    AbstractAlthough the NHC‐catalyzed cyclization reactions have been well established for the synthesis of various heterocycles, the corresponding all carbon cyclization reaction for the synthesis of carbocycles is far less established. In this note, the NHC‐catalyzed all carbon [4+2] cyclocondensation of α,β‐unsaturated acyl chlorides and 3‐alkenyloxindoles was developed to give the corresponding spirocarbocyclic oxindoles in good yield with good to high diastereoselectivities.
