  • 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
    DOI:10.1002/chem.201800957
    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
    开发了一种通过Fe(OTf)3促进的供体-受体环丙烷与硫代酸酯酯加成的[3 + 2]环加成的反式构型四氢噻吩(THT)的合成途径。环加成反应以高收率和高非对映选择性进行,提供了瞬时α-烷氧基THT。不仅芳族和脂族硫代磺酸酯,而且硫代内酯也适用于本发明的铁催化。的产品的S,O -缩酮功能的进一步转化是在一个高度实现反式非对映选择性方式进行。此外,通过对映体富集的反式构型THT的合成,清楚地证明了我们方法的实用性。

    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。

    through a cascade reaction between 2‐isocyanoethylindole and alkylidene malonates catalyzed by a chiral N,N′‐dioxide/MgII catalyst. Fused polycyclic indolines containing three stereocenters were afforded in good yields with excellent diastereo‐ and enantioselectivities through a Michael/Friedel–Crafts/Mannich cascade. When 2‐substituted 2‐isocyanoethylindoles were used, spiroindoline derivatives were obtained
    通过手性N,N'-二氧化物/ Mg II催化剂催化2-异氰基乙基吲哚和亚烷基丙二酸酯之间的级联反应,实现了吲哚的高效不对称脱芳香化。通过Michael / Friedel-Crafts / Mannich级联反应,可以很好地获得具有三个立体中心的熔融多环二氢吲哚,并具有出色的非对映异构和对映选择性。当使用2-取代的2-异氰基乙基吲哚时,螺二氢吲哚衍生物是通过Michael / Friedel-Crafts反应获得的。

    could be recovered and reused ten times, and the results showed a negligible loss of catalytic activity. Various aryl- and heteroarylidene malonates, as well as dimethyl (cyclohexylidene)malonate, were isolated in good to high yields under optimal conditions. The use of hazardous reagents and solvents were minimized in the current method, and separation of catalyst and products, as well as the recovery
    在介孔聚三聚氰胺-甲醛存在下,开发了作为多功能中间体的亚芳基和亚烷基丙二酸酯的有效固态/浆态合成。缩合反应是通过球磨过程在室温下无溶剂条件下进行的,这是一种非常规程序和更环保的方法。介孔多相催化剂可以回收和重复使用十次,结果表明催化活性的损失可以忽略不计。各种芳基和杂亚芳基丙二酸酯以及(亚环己基)丙二酸二甲酯在最佳条件下以良好到高产率分离。本方法最大限度地减少了有害试剂和溶剂的使用,催化剂与产物的分离,以及催化剂的回收和再利用,是通过具有成本效益的程序进行的。这项工作揭示了多孔有机聚合物(POP)中众多路易斯碱位与受体-供体氢键官能团的协同作用,其高孔隙率对促进固相合成中的碳-碳偶联反应起着至关重要的作用。 .

    作者:Manmath Mishra、Pinaki Bhusan De、Sourav Pradhan、Tharmalingam Punniyamurthy
    DOI:10.1021/acs.joc.9b01506
    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)
