  • Ynamide-Mediated Thiopeptide Synthesis
    作者:Jinhua Yang、Changliu Wang、Silin Xu、Junfeng Zhao
    DOI:10.1002/anie.201811586
    日期:2019.1.28
    two‐step strategy for thiopeptide bond formation with readily available monothiocarboxylic acids as thioacyl donors is described. The α‐thioacyloxyenamide intermediates formed from the ynamides and monothiocarboxylic acids can be purified, characterized, and stored. The balance between their activity and stability enables them to act as effective thioacylating reagents to afford thiopeptide bonds under mild
    不足的合成策略不足以将酰胺键位点引入肽主链,因此无法探索作为肽和蛋白质化学生物学工具的酰胺替代物的全部潜力。描述了一种新颖的由酰胺介导的两步策略,用于以易于获得的单羧酸作为代酰基供体的肽键形成。由乙酰胺和一羧酸形成的α-代酰氧烯酰胺中间体可以进行纯化,表征和储存。它们的活性和稳定性之间的平衡使它们能够充当有效的酰化试剂,在温和的反应条件下提供肽键。氨基酸官能团,例如OH,CONH 2,并且在巯基肽合成过程中不需要保护吲哚NH基团。这种策略的模块化性质使得在溶液和固相中都可以将酰胺键定点结合到肽主链中。
  • Regiocontrolled Gold-Catalyzed [2+2+2] Cycloadditions of Ynamides with Two Discrete Nitriles to Construct 4-Aminopyrimidine Cores
    作者:Somnath Narayan Karad、Rai-Shung Liu
    DOI:10.1002/anie.201405312
    日期:2014.8.18
    Reported herein is the novel goldcatalyzed intermolecular [2+2+2] cycloaddition of ynamides with two discrete nitriles to form monomeric 4‐aminopyrimidines, which are pharmaceutically important structural motifs. The utility of this new cycloaddition is demonstrated by the excellent regioselectivity obtained using a variety of ynamides and nitriles.

  • Et2Zn-promoted β-trans-selective hydroboration of ynamide
    作者:Kefeng Wang、Zixi Zhuang、Huihui Ti、Peishan Wu、Xin Zhao、Honggen Wang
    DOI:10.1016/j.cclet.2019.11.008
    日期:2020.6
    Abstract The trans-hydroboration of alkyne represents a challenging task in organic synthesis. Reported herein is an Et2Zn promoted β-trans hydroboration of ynamides by using N-heterocyclic carbene (NHC)-ligated borane as boryl source. The reaction leads to a stereoselective construction of enamides bearing a valuable boryl substituent. Both aromatic and aliphatic ynamides were applicable to the reaction
    摘要炔烃的反式氢化反应是有机合成中的一项艰巨任务。本文报道了通过使用N-杂环卡宾(NHC)连接的硼烷作为源,Et2Zn促进的乙酰胺的β-反式氢化。该反应导致带有有价值的基取代基的酰胺的立体选择性结构。芳族和脂族乙酰胺均适用于该反应。通过Suzuki-Miyaura偶联产物中CB键的合成转化为多取代的酰胺类化合物提供了简单且立体定向的途径。进行了机理研究并讨论了可能的机理
  • Gold-Catalyzed [4+2]- and [3+3]-Annulations of Ynamides with 1-Yn-3-ols to Access Six-Membered Carbocycles and Oxacycles <i>via</i> Three Distinct Cyclizations
    作者:Sovan Sundar Giri、Rai-Shung Liu

    日期:2017.10.4
    and 1‐yn‐3‐ols are described; the resulting carbo‐ and heterocycles were produced efficiently in one‐pot operations using a gold catalyst. The chemoselectivities of these annulations are controlled by variations of the substituents of the ynamides and the 1‐yn‐3‐ols. This reaction sequence involves initial alkoxylations of ynamides, followed by Claisen rearrangement of propargylic enol ethers, and ends
    描述了三种不同的催化酰胺和1-yn-3-ols催化环化的策略;在使用催化剂的一锅操作中有效地生产了碳和杂环。这些环空的化学选择性受炔基和1–yn–3–ol取代基的变化控制。该反应顺序包括ynamides的初始烷氧基化,随后炔烯醇醚的Claisen重排,并结束与6-内-三角函数的1-丙二烯基-5-酰胺中间体的环化反应。在这些级联环中,5-烯基-1-酰胺的环化生成5,6-二氢-2-吡喃酮和6-亚烷基环己基-2-烯-1-羧酰胺在文献中是空前的。
  • Cp*Co(III)-Catalyzed Dearomative [3 + 2] Spiroannulation of 2-Alkenylphenols with Ynamides via C–H Activation
    作者:Peng-Peng Lin、Xiang-Lei Han、Guo-Hua Ye、Ji-Lin Li、Qingjiang Li、Honggen Wang
    DOI:10.1021/acs.joc.9b01750
    日期:2019.10.18
    An oxidative [3 + 2] C-H spiroannulation reaction of 2-alkenylphenols with ynamides has been developed toward the synthesis of spiro[4,5]decane derivatives. This dearomative reaction employs earth-abundant cobalt as the metal catalyst and occurs under rather mild reaction conditions (room temperature). The use of ynamides confers unique reactivity and exclusive regioselectivity. The products bearing
