    Tetrahydro-1,3-oxazepines via Intramolecular Amination of Cyclopropylmethyl Cation
    摘要:
    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.

  • An Expeditious Route to<i>trans</i>-Configured Tetrahydrothiophenes Enabled by Fe(OTf)<sub>3</sub>-Catalyzed [3+2] Cycloaddition of Donor-Acceptor Cyclopropanes with Thionoesters
    作者:Yohei Matsumoto、Daiki Nakatake、Ryo Yazaki、Takashi Ohshima

    日期:2018.4.20
    A synthetic route to trans‐configured tetrahydrothiophenes (THTs) through Fe(OTf)3‐promoted [3+2] cycloaddition of donor–acceptor cyclopropanes with thionoesters was developed. The cycloaddition proceeded in high yield with high diastereoselectivity, affording transient α‐alkoxy THTs. Not only aromatic and aliphatic thionoesters, but also thionolactone were applicable to the present iron catalysis

    amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation
    催化量的InCl 3和乙酸酐的组合显着促进了各种醛和活化的亚甲基化合物的Knoevenagel缩合。该催化体系可容纳含有各种供电子和吸电子基团的芳族醛,杂芳族醛,共轭醛和脂族醛。成功驱动缩合反应系列的关键是双乙酸双酯中间体的形成,该中间体是在铟催化剂的帮助下由醛和酸酐就地生成的。

    The optimized reaction conditions provide a good yield for the radical conjugate addition products (44 examples) with a wide range of structurally different Michael acceptors. A gram scale reaction using sunlight irradiation is also described. Furthermore, several transformations were carried out with the Giese addition products.

    日期:2019.9.6
    Aerobic copper(II)-catalyzed tandem ring opening and oxidative C–H alkylation of donor–acceptor cyclopropanes with bisaryl hydrazones is accomplished to produce tetrahydropyridazines, in which copper(II) plays dual role as a Lewis acid as well as redox catalyst. The reaction is stereospecific, and optically active cyclopropanes can be reacted with high optical purities (89–98% enantiomeric excess)
    好氧铜(II)催化的串联环开环和供体-受体环丙烷与双芳基的氧化CH烷基化反应可制得四氢哒嗪,其中铜(II)既起路易斯酸的作用,又起氧化还原催化剂的作用。该反应具有立体特异性,旋光性环丙烷可以高光学纯度(过量89-98%对映异构体)进行反应。底物范围,官能团耐受性,铜(II)催化剂的双重作用以及使用空气作为氧化剂是重要的实用功能。带有3-溴芳基的产物可以高产率地与硼酸进行Pd催化的Suzuki偶联。
