    A Novel One-Step Approach for the Preparation of α-Amino Acids, α-Amino Amides, and Dipeptides from Azetidine-2,3-diones
    摘要:
    A remarkable reaction of azetidine-2,3-diones with primary as well as secondary amines, and water is presented. Simply by varying the nucleophile, an unprecedented one-step synthesis of alpha-amino acids, alpha-amino amides, and dipeptides, was developed in both the racemic and optically pure forms. The current mechanistic hypothesis invokes a concerted process involving CO extrusion. However, a stepwise pathway can also account for these novel transformations.

    摘要:
    DABCO促进了各种活化的乙烯基系统(包括2-环戊烯-1-酮)与对映体纯的氮杂环丁烷2,3-二酮1的反应,得到了相应的光学纯的Baylis-Hillman加合物2,而没有可检测的差向异构化。然而,α-酮内酰胺1与but-3-yn-2-one的反应不那么成功,从而以低收率得到了相应的β-卤代Baylis-Hillman加合物。在水介质中研究了金属介导的2,3-二溴丙烯与氮杂环丁烷-2,3-二酮1之间的溴代烯丙基化反应。令人惊讶地,铟不能促进α-酮内酰胺1的溴代烯丙基化反应,但是Sn-Hf 4 Cl促进了酮1的溴代烯丙基化。高效地进行了操作,以得到作为单一非对映异构体的溴高烯丙基醇5。在此基础上,开发了用于潜在生物活性的3个取代的3-羟基-β-内酰胺部分的不对称合成的简单快速的方法。

  • Stereoselective NaN3-catalyzed halonitroaldol-type reaction of azetidine-2,3-diones in aqueous media
    作者:Benito Alcaide、Pedro Almendros、Amparo Luna、M. Rosario Torres
    DOI:10.1039/b802011f
    日期:——
    Azetidine-2,3-diones (α-oxo-β-lactams) and bromonitromethane undergo coupling in aqueous media in the presence of catalytic amounts of sodium azide. The stereoselectivity of the process was generally good, proceeding with reasonable anti : syn ratios under substrate control. On this basis, a simple and fast protocol for the synthesis of the potentially bioactive 3-substituted 3-hydroxy-β-lactam moiety has been developed. Besides, 2-azetidinone-tethered 1-halo-1-nitroalkan-2-ols are quite useful building blocks; for example, reactions of the above nitrobromohydrins provided spiranic and fused bicyclic-β-lactams.
    乙基丁二酸二酮(α-氧代-β-内酰胺)和溴硝基甲烷在催化量的叠氮化钠存在下,在水介质中发生偶联反应。该过程的立体选择性通常良好,在底物控制下能获得合理的反式:顺式比率。基于此,我们开发了一种简便快捷的方法来合成潜在生物活性的3-取代-3-羟基-β-内酰胺片段。此外,2-吖丁啶酮连接的1-卤代-1-硝基烷-2-醇是非常有用的构建单元;例如,上述硝基溴氢醇的反应提供了螺旋内酰胺和稠合双环-β-内酰胺。
  • Direct allenol-based stereocontrolled access to substituted (E)-1,3-enynes
    作者:Benito Alcaide、Pedro Almendros、Teresa Martínez del Campo

    A stereoselective synthesis of 1-substituted (E)-2-aryl-but-1-en-3-ynes, including tetrasubstituted alkenes, has been developed from aryl-substituted α-allenols by treatment with the AcCl–NaOH (aqueous) system. This transformation might be explained through the elimination of acetic acid, made up of a δ-hydrogen and the acetate group in the initially formed α-allenic acetate.
    通过用AcCl-NaOH(水溶液)处理,从芳基取代的α-烯醇中开发了一种立体选择性合成的1-取代的(E)-2-芳基-丁-1-烯-3-炔烃,包括四取代的烯烃。 。可以通过消除这种解释来解释这种转变。醋酸由δ-氢和最初形成的α-烯丙基乙酸酯中的乙酸酯基团组成。

    β-Lactam–oxindole hybrids have been synthesized in good yields in a one-pot procedure through efficient and stereoselective capture of an oxonium ylide with azetidine-2,3-diones. The reaction allows high to moderate control of stereoselectivity, depending on the 3-diazo-oxindole precursor and the hydroxylic compound used. Two new quaternary stereogenic centers were formed; the stereochemistry at the

    日期:2005.9.19
    A novel regioselective metal-catalyzed spirocyclization of alpha-allenols-cross coupling (Heck, Sonogashira, and Suzuki) reaction sequence, leading to potentially bioactive spirocyclic lactam derivatives has been developed. Precursors for the tandem spirocyclization-coupling reaction, alpha-allenols 2 a-d were obtained starting from alpha-oxolactams 1 a-c via indium-mediated Barbier-type carbonyl-allenylation

    Novel, simple, and convenient strategies to diversely functionalized spirocyclic β-lactams have been developed by using different metal-mediated carbonyl addition/cyclization reaction sequences. Spirocyclization precursors, 2-azetidinone-tethered homoallylic alcohols, bromohomoallylic alcohols, homopropargylic alcohols, (buta-1,3-dien-2-yl)methanols, and α-allenols have been obtained by regioselective
