  • Regioselective Synthesis of 5-Metalated 2-Pyrones by Intramolecular Oxymetalation of Carbonyl-ene-yne Compounds Using Indium Trihalide
    作者:Tetsuji Yata、Yuji Kita、Yoshihiro Nishimoto、Makoto Yasuda
    DOI:10.1021/acs.joc.9b02186
    日期:2019.11.1
    The oxyindation of carbonyl-ene-yne compounds with indium trihalides proceeded efficiently to give di-, tri-, and tetrasubstituted 2-pyrones bearing a carbon-indium bond. The metalated 2-pyrone and a zwitterion intermediate were identified by X-ray crystallographic analysis. The application of organoindium compounds to oxidation or cross-coupling provided easy access to various multifunctionalized
    有效地进行羰基-烯-炔化合物与三卤化的氧化,得到带有碳-键的二,三和四取代的2-吡喃酮。通过X射线晶体学分析鉴定了属化的2-吡喃酮和两性离子中间体。有机化合物在氧化或交叉偶联中的应用使人们容易获得各种多功能的2-吡喃酮。一些2-吡喃酮生物仅在固态(聚集诱导的发射)中显示强荧光。
  • Tetrahydro-1,3-oxazepines via Intramolecular Amination of Cyclopropylmethyl Cation
    作者:Marija Skvorcova、Liene Grigorjeva、Aigars Jirgensons
    DOI:10.1021/acs.orglett.5b01014
    日期:2015.6.19
    An efficient synthesis of tetrahydro-1,3-oxazepines was developed involving the regioselective intramolecular amination of cyclopropylmethyl cation. The cation was generated by the abstraction of one imidate group in bis-imidate bearing a carbocation-stabilizing substituent. Using 1,1,2,3-tetrasubstituted cyclopropane substrates, highly diastereoselective intramolecular amination to trans-tetrahydro-1,3-oxazepines was achieved. The resulting tetrahydro-1,3-oxazepines were transformed to the homoallylamine derivatives in high yields.
  • Three-Component Reaction of Dimethyl Malonate with α,β-Acetylenic Aldehydes and Amines. Synthesis of Push–Pull Buta-1,3-dienes
    作者:S. A. Sokov、I. S. Odin、S. S. Zlotskii、A. A. Golovanov
    DOI:10.1134/s1070428020100140
    日期:2020.10
    Three-component reaction of dimethyl malonate with alpha,beta-acetylenic aldehydes and cyclic secondary amines (pyrrolidine, piperidine, morpholine, and piperazine) under mild conditions afforded dimethyl 2-(3-aminoprop-2-en-1-ylidene)malonates in 50-91% yields. The products were formed preferentially as E isomers, and the described reaction provides a convenient method for the synthesis of push-pull buta-1,3-dienes that are interesting as fluorescent, solvatochromic, and nonlinear optical materials and starting compounds in the synthesis of carbo- and heterocycles. A plausible reaction mechanism involves Knoevenage condensation of dimethyl malonate with alpha,beta-acetylenic aldehyde to give dimethyl 2-(prop-2-yn-1-ylidene)malonate and subsequent nucleophilic addition of cyclic amine to the latter.
