  • Organic synthesis via magnetic attraction: benign and sustainable protocols using magnetic nanoferrites
    作者:R. B. Nasir Baig、Rajender S. Varma
    DOI:10.1039/c2gc36455g
    日期:——
    Magnetic nano-catalysts have been prepared using simple modification of iron ferrites. The nm size range of these particles facilitates the catalysis process, as an increased surface area is available for the reaction; the easy separation of the catalysts by an external magnet and their recovery and reuse are additional beneficial attributes. Glutathione bearing nano-ferrites have been used as organocatalysts for the Paal–Knorr reaction and homocoupling of boronic acids. Nanoferrites, post-synthetically modified by ligands, were used to immobilize nanometals (Cu, Pd, Ru, etc.) which enabled the development of efficient, sustainable and green procedures for azide–alkynes-cycloaddition (AAC) reactions, C–S coupling, O-allylation of phenol, Heck-type reactions and hydration of nitriles.
    通过简单修饰氧体,已制备出磁性纳米催化剂。这些粒子处于纳米尺寸范围,有助于催化过程,因为反应可利用增加的表面积;外部磁易于分离催化剂,并可回收和重复使用,这些是额外的有益特性。负载谷胱甘肽纳米铁氧体已用作有机催化剂,用于PAAl-Knorr反应和硼酸的均偶联。通过配体后合成改性的纳米铁氧体,用于固定纳米属(等),从而实现了高效、可持续和绿色的叠氮-炔烃环加成(AAC)反应、碳-偶联、的烯丙基化、 Heck型反应和腈的合反应的方法发展。
  • Magnetic nanoparticle-supported glutathione: a conceptually sustainable organocatalyst
    作者:Vivek Polshettiwar、Babita Baruwati、Rajender S. Varma

    日期:——
    A conceptually novel nanoparticle-supported and magnetically recoverable organocatalyst has been developed, which is readily prepared from inexpensive starting materials in a truly sustainable manner; which catalyzes the Paal–Knorr reaction with high yield in pure aqueous medium that avoids the use of toxic organic solvents, even in the workup step.
    开发了一种概念上新颖的纳米粒子支持和可磁性回收的有机催化剂,该催化剂可以通过真正可持续的方式,利用廉价的原材料轻松制备。它在纯相介质中催化Paal–Knorr反应,具有高产率,避免了使用有毒有机溶剂,甚至在后处理步骤中也不例外。
  • Enantioselective Synthesis of <i>N</i>-Benzylic Heterocycles: A Nickel and Photoredox Dual Catalysis Approach
    作者:Cristofer Pezzetta、Davide Bonifazi、Robert W. M. Davidson
    DOI:10.1021/acs.orglett.9b03338
    日期:2019.11.15
    Reported herein is a dual nickel- and photoredox-catalyzed modular approach for the preparation of enantioenriched N-benzylic heterocycles. α-Heterocyclic carboxylic acids, easily obtainable from common commercial material, are reported as suitable substrates for a decarboxylative strategy in conjunction with a chiral pyridine–oxazoline (PyOx) ligand, providing quick access to enantioenriched drug-like
    本文报道了用于制备对映体富集的N-苄基杂环的双重和光氧化还原催化的模块化方法。据报道,很容易从常见的商业原料中获得的α-杂环羧酸与手性吡啶-恶唑啉(PyOx)配体一起用作脱羧策略的合适底物,可快速获得对映体富集的类药物产品。已表明在杂环部分上存在指导基团是有益的,在许多情况下提供了改进的立体选择性。
  • Synthesis and Characterization of Chiral Conducting Polymers Based on Polypyrrole
    作者:Fang Chen、Parveen Akhtar、Leon A. P. Kane-Maguire、Gordon G. Wallace
    DOI:10.1071/c96189
    日期:——

    A range of optically active pyrrole monomers have been synthesized in which a chiral sub- stituent is covalently bonded either to the pyrrole N or C3 ring position, namely (–)-(1R)-4-methyl-N-(1-phenylethyl)pyrrole-3-carboxamide, (+)-(1S)-4-methyl-N-(1-phenylethyl)pyrrole-3-carboxamide, (–)-(1R)-4-methyl-N-(1-naphthylethyl)pyrrole-3-carboxamide, (+)-(1S)-4-methyl-N-(1-naphthylethyl)pyrrole-3-carboxamide, (+)-(2S)-2-(1H-pyrrol-1-yl)propionic acid, (+)-(1S)-N-(1-phenyl-ethyl)pyrrole, and (–)-(1R)-N-(1-phenylethyl)pyrrole. Their chiroptical properties have been established by circular dichroism spectroscopy. Electropolymerization of the three N-substituted pyrrole monomers provided films of chiral conducting polymers, whose electrical and spectroscopic properties are described. Although oxidation of the C3 substituted pyrrole monomers was also facile, electrodeposition was poor and films of the associated polymers could not be obtained.
