  • Hydroalkylation leading to heterocyclic compounds. Part 1: New strategies for the synthesis of polysubstituted 2H-pyran-2-ones
    作者:Wei-Bing Liu、Huan-Feng Jiang、Chun-Li Qiao
    DOI:10.1016/j.tet.2008.12.069
    日期:2009.3
    Polysubstituted 2H-pyran-2-ones and 5,6-dihydro-2H-pyran-2-ones were synthesized via the MCRs initiated by the hydroalkylation of alkynoates with activated methylenes. Under the optimized reaction conditions, the desired products were obtained in 47–88% isolated yields. The experimental results showed that the groups on activated methylenes act important roles in the nucleophilic attack fashion.
    经由MCR合成多取代的2 H-吡喃-2-酮和5,6-二氢-2 H-吡喃-2-酮,所述MCR是通过炔烃与活化的亚甲基的加氢烷基化反应而引发的。在优化的反应条件下,所需产物的分离产率为47-88%。实验结果表明,活化亚甲基上的基团以亲核攻击方式起着重要作用。
  • Synthesis of Polysubstituted α-Pyrones Using Zinc-Catalyzed Addition-Cyclization Reactions
    作者:Wei-Bing Liu、Cui Chen、Qing Zhang、Zhi-Bo Zhu
    DOI:10.1002/jhet.1698
    日期:2014.9
    Various polysubstituted α‐pyrone derivatives have been directly synthesized via a hydroalkylation of Michael additional reaction following a cyclized process catalyzed by the Lewis acid of Zn(OAc)2. This protocol provides a new convenient and step‐economical route to construct heterocycles. Fourteen examples are obtained from easily available materials with moderate to good yields.
    在Zn(OAc)2的路易斯酸催化的环化过程之后,通过迈克尔附加反应的加氢烷基化反应已直接合成了各种多取代的α-吡喃酮衍生物。该协议为构建杂环化合物提供了一种新的便捷且经济的途径。从容易获得的材料中获得了十四个示例,它们具有中等到良好的产率。
  • Construction of Functionalized 2<i>H</i>-Pyran-2-ones via N-Heterocyclic Carbene-Catalyzed [3 + 3] Annulation of Alkynyl Esters with Enolizable Ketones
    作者:Zheng Liang、Jibin Li、Lei Wang、Zexuan Wei、Jiahui Huang、Xinrui Wang、Ding Du
    DOI:10.1021/acs.joc.2c02392
    日期:2023.2.3
    A new synthesis of functionalized 2H-pyran-2-ones has been developed through N-heterocyclic carbene-catalyzed formal [3 + 3] annulation of alkynyl esters with enolizable ketones. The key to the success of this protocol relies on the use of an NHC instead of a tertiary amine as the catalyst. This protocol also features a broad substrate scope and mild metal-free conditions, offering simple and rapid
    通过 N-杂环卡宾催化的炔基酯与可烯醇化酮的正式 [3 + 3] 环化,开发了功能化 2 H -pyran-2-ones的新合成方法。该协议成功的关键在于使用 NHC 而不是叔胺作为催化剂。该协议还具有广泛的底物范围和温和的无金属条件,以高度区域选择性的方式提供对目标分子的简单快速访问。
  • Divergent NHC-Catalyzed Oxidative Transformations of 3-Bromoenal: Selective Synthesis of 2<i>H</i>-Pyran-2-ones and Chiral Dihydropyranones
    作者:Gang Wang、Xia Chen、Gaohan Miao、Weijun Yao、Cheng Ma
    DOI:10.1021/jo400950j
    日期:2013.6.21
    A selective synthesis of either 2H-pyran-2-ones (4) or chiral dihydropyranones (6) from the same substrates of 3-bromoenals and 1,3-dicarbonyl compounds upon oxidative N-heterocyclic carbene catalysis is presented. It is shown that the oxidative transformation of 3-bromoenals under NHC catalyst can be well controlled to proceed through two pathways, i.e., elimination of reducible β-bromide or by an
    提出了在氧化的N-杂环卡宾催化下,由3-溴烯醛和1,3-二羰基化合物的相同底物选择性合成2 H-吡喃-2-酮(4)或手性二氢吡喃酮(6)的方法。结果表明,可以很好地控制NHC催化剂下3-溴烯醛的氧化转化,通过两条途径进行,即消除可还原的β-溴化物或通过外部氧化剂3进行,从而选择性地产生两种不饱和酰基偶氮,分别。
