  • The Reaction of Meldrum's Acid and Its Derivatives with Conjugated Azoalkenes: A Convenient Route to 1-Amino-1<i>H</i>-pyrrol-2(3<i>H</i>)-ones
    作者:Antonio Arcadi、Orazio A. Attanasi、Zhiyuan Liao、Franco Serra-Zanetti
    DOI:10.1055/s-1994-25532
    日期:——
    The reaction of Meldrum's acid and its 5-substituted derivatives with conjugated azoalkenes in the presence of triethylamine produces, via 1,4-conjugate addition, corresponding hydrazones which undergo decarboxylative alcoholysis and simultaneous cyclization to give 3-unsubstituted and 3-monosubstituted 1-amino-1H-pyrrol-2-(3H)-ones respectively.
    在三乙胺存在下,Meldrum酸及其5-取代衍生物与共轭叠氮烯进行1,4-共�配加成反应,生成相应的腙,这些腙随后发生脱羧醇解反应并同步环化,分别形成3-未取代和3-单取代的1-氨基-1H-吡咯-2-(3H)-酮。

  • Multi-catalysis cascade reactions based on the methoxycarbonylketene platform: diversity-oriented synthesis of functionalized non-symmetrical malonates for agrochemicals and pharmaceuticals
    作者:Dhevalapally B. Ramachary、Chintalapudi Venkaiah、Y. Vijayendar Reddy、Mamillapalli Kishor
    DOI:10.1039/b901652j
    日期:——
    In this paper we describe new multi-catalysis cascade (MCC) reactions for the one-pot synthesis of highly functionalized non-symmetrical malonates. These metal-free reactions are either five-step (olefination/hydrogenation/alkylation/ketenization/esterification) or six-step (olefination/hydrogenation/alkylation/ketenization/esterification/alkylation), and employ aldehydes/ketones, Meldrum's acid, 1,4-dihydropyridine/o-phenylenediamine, diazomethane, alcohols and active ethylene/acetylenes, and involve iminium-, self-, self-, self- and base-catalysis, respectively. Many of the products have direct application in agricultural and pharmaceutical chemistry.
    在本文中,我们描述了一种新的多重催化级联反应(MCC),用于一锅合成高度功能化的非对称马来酸酯。这些无金属催化反应分为五步(烯化/加氢/烷基化/酮化/酯化)或六步(烯化/加氢/烷基化/酮化/酯化/烷基化),涉及醛/酮、梅尔德伦酸、1,4-二氢吡啶/邻苯二胺、重氮甲烷、醇以及活性乙烯/炔烃,分别涉及亚胺、各自、自我、自我和碱催化。许多产品在农业和制药化学中具有直接应用。
  • Mn(III)-based oxidative free-radical cyclizations of alkenyl Meldrum's acids
    作者:Barry B. Snider、Rachel B. Smith
    DOI:10.1016/s0040-4020(01)01054-7
    日期:2002.1
    Oxidative cyclization of unsaturated Meldrum's acids can be carried out at temperatures as low as −30°C. The rate-determining step is cyclization of the enolate to the alkene (11 to 14 and 15) rather than enolization, which is the rate-determining step with dimethyl 4-pentenylmalonate (1). While cyclization of 1 gives mainly cyclopentanes, cyclization of Meldrum's acids provides a versatile route to
    不饱和麦德鲁姆酸的氧化环化反应可在低至-30°C的温度下进行。速率确定步骤是烯醇盐环化成烯烃(11至14和15)而不是烯化,这是用4-戊烯基丙二酸二甲酯(1)确定速率的步骤。虽然1的环化主要产生环戊烷,但Meldrum酸的环化提供了通往环己烯的通用途径。
