  • One-pot reductive coupling of N-acylcarbamates with activated alkenes: application to the asymmetric synthesis of pyrrolo[1,2-a]azepin-5-one ring system and (−)-xenovenine

    日期:——
    cyclic N-acylcarbamates can be used as stable substrates, and a range of activated alkenes serve as effective radical receptors. The reductive coupling of l-N-acylcarbamates 12/13 gave 2,5-disubstituted pyrrolidine derivatives in high trans-diastereoselectivities. The reductive coupling with penta-2,4-dienoate proceeded exclusively in a 1,6-addition fashion, producing a single non-conjugated E-isomer
    描述了N-酰基氨基甲酸酯与活化的烯烃的一锅还原还原。该方法基于用DIBAL-H部分还原N-酰基氨基甲酸酯,然后形成N-酰基亚胺离子和SmI(2)介导的与活化烯烃的自由基偶联。无环和环状N-酰基氨基甲酸酯均可用作稳定的底物,并且一系列活化的烯烃可用作有效的自由基受体。1N-酰基氨基甲酸酯的还原偶联以高反式非对映选择性产生2,5-二取代的吡咯烷衍生物。与2,4-戊二酸五酯的还原偶联仅以1,6-加成方式进行,产生单个非共轭的E-异构体。在此方法的基础上,三步构建了吡咯并[1,2-a]氮杂环庚烷-5-酮16,该骨架是许多茎类生物碱和来咪唑定生物碱的骨架,
  • Efficient and Expeditious Protocols for the Synthesis of Racemic and Enantiomerically Pure Endocyclic Enecarbamates from <i>N</i>-Acyl Lactams and <i>N</i>-Acyl Pyrrolidines
    作者:Denilson F. Oliveira、Paulo C. M. L. Miranda、Carlos R. D. Correia
    DOI:10.1021/jo9903297
    日期:1999.9.1
    A mild, practical, and straightforward protocol for the construction of endocyclic enecarbamates starting from N-acyl lactams and N-acyl pyrrolidines is presented. Lactams were reduced to the corresponding alpha-hydroxycarbamates in good to excellent yields using DIBAL-H, SuperHydride, or NaBH(4) followed by beta-elimination (dehydration) promoted by trifluoroacetic anhydride in the presence of hindered
    提出了从N-酰基内酰胺和N-酰基吡咯烷类开始构建内环烯氨基甲酸酯的温和,实用和直接的方案。使用DIBAL-H,SuperHyride或NaBH(4)将内酰胺以良好的优异产率还原为相应的α-羟基氨基甲酸酯(4),然后在受阻硝化碱(如2,6)的存在下,由三氟乙酸酐促进β-消除(脱水) -二甲基吡啶,二异丙基乙胺或三乙胺。该方案的微小变化允许制备几种内环烯氨基甲酸酯(12个实例),总产率良好至优异(56-96%)。已证明该方案适用于多种环大小,与不同的保护基团兼容,并且足够温和以防止易于消旋的立体中心消旋。
  • Synthesis of highly functionalized 2,5-disubstituted pyrrolidines via an aza-Morita–Baylis–Hillman-type reaction
    作者:James E. Kitulagoda、Anders Palmelund、Varinder K. Aggarwal
    DOI:10.1016/j.tet.2010.05.047
    日期:2010.8
    An aza-Morita-Baylis-Hillman-type reaction of Michael acceptors with 5-substituted cyclic N,O-acetals derived from pyrrolidines has been investigated. It has been found that the combination of Me2S and TMSOTf work well with unhindered and reactive enals and enones whilst the use of quinuclidine and TMSOTf is superior for more hindered Michael acceptors. The reactions lead to 2,5-trans-disubstituted pyrrolidines with good to excellent diastereoselectivity. The origin of the selectivity is discussed. (C) 2010 Elsevier Ltd. All rights reserved.
  • Probing the functional requirements of the l-haba side-chain of amikacin—synthesis, 16S A-site rRNA binding, and antibacterial activity
    作者:Stephen Hanessian、Alexander Kornienko、Eric E Swayze
    DOI:10.1016/s0040-4020(02)01625-3
    日期:2003.2
    The 1-amino group in amikacin was acylated with a variety of 2-hydroxy aminocarboxylic acids to probe the effect of acylation on ribosomal binding and antibacterial activity. The N-hydroxy urea analogue of amikacin (8a) in which the 2-S-hydroxyl-bearing carbon was replaced by an N-OH group was equally active against S. aureus and E. coli in vitro. The analogous tobramycin variant 9 was more active than amikacin. (C) 2003 Elsevier Science Ltd. All rights reserved.
  • Vinylogous Mannich reactions. Stereoselective formal synthesis of pumiliotoxin 251D
    作者:Stephen F. Martin、Scott K. Bur
    DOI:10.1016/s0040-4020(99)00452-4
    日期:1999.7
    A concise synthesis of (−)-3, a known precursor of pumiliotoxin 251D, has been completed using a vinylogous Mannich reaction as a key construction. Silyloxyfuran 10 added to methoxypyrrolidine 20 in the presence of TMS-OTf to give a mixture (4.8:1) of 21 and 22 in 57% yield. Reduction and global deprotection of 21 afforded the bicyclic lactam 23. Raney Nickel mediated extrusion of the hydroxymethyl
    使用乙烯基曼尼希反应作为关键结构,完成了已知的pumiliotoxin 251D前体(-)- 3的简明合成。在TMS-OTf存在下,将甲硅烷氧基呋喃10加至甲氧基吡咯烷20中,以57%的收率得到21和22的混合物(4.8:1)。还原和整体脱保护的21提供了双环内酰胺23。Raney Nickel介导的23羟甲基的挤出得到(-)- 3。
