    Tandem cross-Rauhut–Currier/cyclization reactions of activated alkenes to give densely functionalized 3,4-dihydropyrans
    摘要:
    A novel tandem cross-Rauhut-Currier/cyclization reaction between alpha,beta-unsaturated ketones was developed. Using DABCO (20 mol %) as the catalyst, a series of densely functionalized 3,4-dihydropyrans were obtained in excellent yields and stereoselectivities (up to 98% yield, >99:1 dr). A tentative catalytic cycle was proposed with key intermediates confirmed by ESIMS studies. (C) 2011 Elsevier Ltd. All rights reserved.

  • Facile synthesis of polysubstituted furans and dihydrofurans via cyclization of bromonitromethane with oxodienes
    作者:Rongshun Chen、Xia Fan、Zhaozhong Xu、Zhengjie He
    DOI:10.1016/j.tetlet.2017.08.027
    日期:2017.9
    A series of polysubstituted furans and dihydrofurans have been prepared from readily available oxodienes and bromonitromethane in modest to excellent yields. This facile synthetic method is developed on the basis of proprietary properties of nitro group such as strong electron-withdrawing ability and cleavability. The conversion of nitro-substituted dihydrofurans to furans is presumably realized by
    已经从容易获得的氧二烯和溴硝基甲烷以中等至优异的产率制备了一系列多取代的呋喃和二氢呋喃。这种简便的合成方法是基于硝基的专有特性(如强大的吸电子能力和可裂解性)而开发的。硝基取代的二氢呋喃向呋喃的转化大概是通过在DABCO的帮助下消除HNO 2来实现的。
  • Construction of CF<sub>3</sub>-Functionalized Fully Substituted Benzonitriles through Rauhut–Currier Reaction Initiated [3 + 3] Benzannulation

    Though numerous cyanation reactions have been developed for the synthesis of benzonitriles, the construction of valuable fully substituted benzonitriles is still a challenging task. Herein, we reported a tertiary amine-catalyzed [3 + 3]-benzannulation for the green synthesis of CF3-functionalized fully substituted benzonitriles. This strategy features exclusive chemoselectivity, high atom-economy,
    尽管已经开发了许多用于合成苯甲腈的氰化反应,但构建有价值的完全取代的苯甲腈仍然是一项具有挑战性的任务。在此,我们报道了一种叔胺催化的 [3 + 3] -苄基化反应,用于绿色合成 CF 3官能化的完全取代的苄腈。该策略具有独特的化学选择性、高原子经济性和良好的阶梯经济性,以及环境友好的试剂和温和的条件。使用这种方法可以快速构建独特的三苯基取代的二氰基苯甲酸酯产品。成功的放大合成证明了该反应的实用性和可靠性。一项机理研究表明 [3 + 3]-benzannulation 是由分子间 Rauhut-Currier 反应引发的。
  • N-Heterocyclic Carbene Catalyzed [4+2] Cycloaddition of Nitroalkenes with Oxodienes
    作者:Xiang-Yu Chen、Li-Hui Sun、Song Ye
    DOI:10.1002/chem.201204539
    日期:2013.4.2
    NHC catalysis: N‐heterocyclic carbenes were found to be efficient catalysts for the unprecedented [4+2] cycloaddition of nitroalkenes and oxodienes, giving the corresponding dihydropyrans in good yield with good diastereoselectivity (see scheme). Deuteration experiment reveals that the reaction is possibly initiated by the addition of N‐heterocylic carbene to nitroalkenes.
    NHC催化:N-杂环卡宾被发现是硝基烯烃和氧二烯前所未有的[4 + 2]环加成反应的有效催化剂,从而以高收率和良好的非对映选择性提供相应的二氢吡喃(参见方案)。氘化实验表明,该反应可能是通过在硝基烯烃中添加N-杂环卡宾而引发的。

    Herein, we report substituent-controlled divergent cascade cycloaddition reactions of chalcones and arylalkynols in the presence of PtI2. Depending on the substituent on the chalcone, either spiroketals or oxa-bridged fused heterocycles could be obtained in the ranges of 86–97% and 87–95% yields under identical reaction conditions. Control experiments were carried out to elucidate the origin of the
    在此,我们报告了在 PtI 2存在下查耳酮和芳基炔醇的取代基控制的发散级联环加成反应。根据查耳酮上的取代基,在相同的反应条件下,可以以 86-97% 和 87-95% 的产率获得螺缩酮或氧杂桥连的稠合杂环。进行对照实验以阐明高化学选择性的起源。这些为合成各种结构复杂的含氧杂环提供了一种方法。
  • Organocatalytic Asymmetric [4+2] Cycloaddition of 1-Acetylcyclopentene and 1-Acetylcyclohexene for the Synthesis of Fused Carbocycles
    作者:Utpal Nath、Subhas Chandra Pan
    DOI:10.1002/ejoc.201701238
    日期:2017.11.24
    The first organocatalytic asymmetric [4+2] cycloaddition reaction employing 1-acetylcyclopentene and 1-acetylcyclohexene is described. Enones having cyano group are used as the dienophile partner in this method. The reaction provides a useful practical route for the synthesis of bicyclic fused carbocycles having four contiguous stereocentres.
