    单一有机光催化剂对 N-芳基叔胺与重氮乙酸酯的吲哚化反应
    摘要:
    重氮乙酸酯广泛用于合成高价值的吲哚。以前的研究主要集中在使用金属卡宾反应性或重氮乙酸盐的先天亲核性通过传统的双电子途径产生吲哚。然而,这些策略受到过渡金属、氧化剂或底物预功能化需求的限制。为了克服这些局限性,我们在此报告了一种开壳策略,该策略首次利用重氮乙酸盐的自由基反应性合成吲哚,特别是对于更有价值的 [ a]-环状吲哚。值得注意的是,这种可见光驱动的转化是由单一的有机光催化剂实现的,无需金属或添加剂。初步的机理研究和密度泛函理论计算揭示了一种中继可见光光氧化还原催化过程,该过程可能涉及在使用一种有机光催化剂的单个操作中进行多个离散的光氧化还原催化循环。

    This invention relates to ionic liquid (ILs) solvents for chemical synthesis based on an alkyl - imidazolium cation core containing ionic liquids which have enhanced biodegradability and reduced toxicity relative to existing imidazolium bases ILs such as 1-butyl-3-methylimidazolium (bmmim) salts. Many of the described ILs produce a score of over 60% biodegradability over 28 days in a biodegradability test such as the Sturm Test, the Closed Bottle Test (OECD 301D) or the CO2 Headspace Test (ISO 14593). The ILs of the invention comprise an alkyl substituted imidazolium cationic core having a -C=OX- side chain in the 3-position of the imidazole ring, wherein X = O, NH, N or S and an associated counteranion characterized in that the -C=OX side chain comprises at least one ether linkage. The biodegradable and non-toxic IL may be used as green solvents for the chemical, pharmaceutical, biofuel and biomass industries. The ILs of the invention are particularly useful in hydrogenation, pericyclic and metathesis reactions.
    这项发明涉及一种基于含有烷基-咪唑啉阳离子核心的离子液体溶剂,用于化学合成,这些离子液体相对于现有如1-丁基-3-甲基咪唑啉(bmmim)盐类的咪唑啉基离子液体,具有增强的生物降解性和降低的毒性。所描述的许多离子液体在生物降解性测试中,例如Sturm测试、封闭瓶测试(OECD 301D)或CO2顶空测试(ISO 14593)中,28天内生物降解率超过60%。本发明的离子液体包括一个在咪唑啉环的3位上带有-C=OX-侧链的烷基取代咪唑啉阳离子核心,其中X=O,NH,N或S,以及一个相关的反离子,其特征在于-C=OX侧链至少包含一个醚键。这些生物降解且无毒的离子液体可作为化学、制药、生物燃料和生物质工业的绿色溶剂。特别是,本发明的离子液体在氢化、周环和复分解反应中非常有用。

    作者:Saibh Morrissey、Bruce Pegot、Deborah Coleman、M. Teresa Garcia、Damien Ferguson、Bríd Quilty、Nicholas Gathergood
    DOI:10.1039/b812809j
    日期:——
    A series of imidazolium ionic liquids was prepared and screened against 7 bacterial strains. The incorporation of ether groups into the ester side-chain significantly reduced the toxicity compared with alkyl ester derivatives. Biodegradation data are also presented for 15 of the ionic liquids—including 6 examples which can be classed as readily biodegradable.
    制备了一系列咪唑离子液体,并对7种细菌菌株进行了筛选。在酯侧链中引入醚基团与烷基酯衍生物相比显著降低了毒性。本文还提供了其中15种离子液体的生物降解数据,其中包括6个可归类为易生物降解的例子。
  • Tandem ionic liquid antimicrobial toxicity and asymmetric catalysis study: carbonyl-ene reactions with trifluoropyruvate
    作者:Rohitkumar G. Gore、Thi-Kim-Thu Truong、Milan Pour、Lauren Myles、Stephen J. Connon、Nicholas Gathergood
    DOI:10.1039/c3gc40875b
    日期:——
    The asymmetric carbonyl-ene reaction of trifluoropyruvate with five alkenes catalysed by [Pd(R)-BINAP}](SbF6)2 were carried out in good yields and enantioselectivities (up to 96% yield and 96% ee) in low antimicrobial toxicity C2-substituted imidazolium ionic liquids (ILs). Toxicity data was included in the selection criteria for reaction optimisation after a preliminary IL screen. The Pd(II) catalyst immobilised in an IL was recycled and reused up to 7 times without decrease of either yield or ee. One IL prepared, which was determined to be of high antimicrobial toxicity was assigned a low priority for future applications.
    在低抗菌毒性的C2取代咪唑鎓离子液体(ILs)中,三氟丙酮酸与五种烯烃的非对称羰基-烯反应在[Pd(R)-BINAP}](SbF6)2催化下,实现了良好的产率和立体选择性(最高达96%产率和96% ee)。在初步的IL筛选后,毒性数据被纳入反应优化的选择标准。固定在IL中的Pd(II)催化剂可回收并重复使用多达7次,且产率和ee均无下降。一种制备的IL被确定具有高抗菌毒性,因此被赋予低优先级用于未来的应用。
