Spirulina (Arthrospira) platensis Supported Ionic Liquid as a Catalyst for the Synthesis of 3-Aryl-2-oxazolidinones from Carbon Dioxide, Epoxide, Anilines

Abstract: This study investigates the potential application of the (Ammonio)butane-1-sulfonate modified Spirulina (Arthrospira) platensis biomasses in the synthesis of 3-aryl-2-oxazolidinones from CO2, ethylene oxide, and anilines. High catalytic activity and ease of recovery from the reaction mixture using filtration and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system. The effects of the structure of ionic liquid on the catalytic performance were investigated and the various reaction conditions were optimized. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion. Graphical Abstract: [Figure not available: see fulltext.].

The Synthesis of 3-Aryl-2-oxazolidinones from CO2, Ethylene Oxide, and Anilines Under Mild Conditions Using PVA-DFNT/Ni

Abstract: A novel nanocatalyst design using nanomaterials through active-zone crystallisation was proposed. The hydrothermal crystallisation of amorphous dendritic fibrous nano-titanium dioxide with Ni (DFNT/Ni) sites was determined to be the main step in producing extremely active dendritic DFNT/Ni zones, which in turn dramatically enhanced their catalytic activities. DFNT/Ni was then combined with polyvinyl alcohol (PVA) by using a traditional individual-nozzle electrospinning method, and the resulting material was named PVA-DFNT/Ni. This method was utilised to produce 3-aryl-2-oxazolidinones from ethylene oxide, CO2, and anilines. The prepared catalytic apparatus was eco-friendly and had the advantages of high catalytic activity, ability to improve the reaction mixture, and reusability without a considerable decrease in efficiency. It is extracted in the straight and adoptive chemical fixation of flue-gas CO2 obtained from industrial emissions, thereby achieving high degrees of CO2 absorption and conversion.

Synthesis of Oxazolidinones and Derivatives through Three-Component Fixation of Carbon Dioxide

An effective three-component fixation of atmospheric CO2 with readily available 1,2-dichloroethane and aromatic amine toward oxazolidinones catalyzed by in situ NHC was developed. The reaction occurred in good to excellent yields with good gene

Synthesis of N-aryl-2-oxazolidinones from cyclic carbonates and aromatic amines catalyzed by bio-catalyst

A convenient and effective method of synthesizing 3-aryl-2-oxazolidinones from cyclic carbonates and aryl amines catalyzed by bio-catalyst adenine in the presence of Et3N under solvent-free conditions is described. The protocol is suitable for the wide scope of substrates, e.g. cyclic carbonates with or without substitutes, and aryl amines with either electron-withdrawing or electron-donating group. The products were obtained in good to excellent yields under the optimal conditions, even in steric hindered cases. The effect of reaction time, temperature, loading of catalyst, and amount of starting materials in the reaction were investigated, and the reaction mechanism is discussed.

LIM KINASE INHIBITORS

A dynamic actin cytoskeleton is necessary for viral entry, intracellular migration, and virion release. For the human immunodeficiency virus (HIV), during viral entry, the virus triggers early actin activity through hijacking chemokine coreceptor signalin

A straightforward one-pot synthesis of bioactive: N -aryl oxazolidin-2-ones via a highly efficient Fe3O4@SiO2-supported acetate-based butylimidazolium ionic liquid nanocatalyst under metal- and solvent-free conditions

In the present study, we report the fabrication and characterization of novel acetate-based butylimidazolium ionic liquid immobilized silica-coated magnetic nanoparticles (IL-OAc@FSMNP). The synthesized nanocomposite proves its supremacy as an environmentally benign catalyst in the reaction of aniline and its derivatives with ethylene carbonate to form bioactive N-aryl oxazolidin-2-ones under metal-, ligand-, and solvent-free conditions. The catalyst offers excellent assemblies of hydrogen-bond donors and acceptors, which activate the substrates, thereby delivering good-to-excellent product yields with a conversion and selectivity of more than 99%. Additionally, mild reaction conditions, wide substrate scope, effortless catalytic recovery and recyclability of the catalyst up to eight consecutive cycles offer the potential for scale-up in various pharmaceutical applications.

Chemoselective Copper-Catalyzed Ullmann-Type Coupling of Oxazolidinones with Bromoiodoarenes

We describe the highly selective copper-catalyzed Ullmann-type coupling of bromoiodoarenes with oxazolidinones. 3,4,7,8-Tetramethyl-1,10-phenanthroline (Me4Phen) was identified as an optimal ligand promoting the desired C-N bond formation, while minimizing the competitive bromo-iodo exchange pathway that leads to formation of iodo-substituted and bis-coupled side products. The developed method is highly selective with a >98:2 ratio of the bromo- vs iodo-substituted compounds obtained in the isolated products.

A One-Pot Synthesis of N-Aryl-2-Oxazolidinones and Cyclic Urethanes by the Lewis Base Catalyzed Fixation of Carbon Dioxide into Anilines and Bromoalkanes

The multicomponent assembly of pharmaceutically relevant N-aryl-oxazolidinones through the direct insertion of carbon dioxide into readily available anilines and dibromoalkanes is described. The addition of catalytic amounts of an organosuperbase such as Barton's base enables this transformation to proceed with high yields and exquisite substrate functional-group tolerance under ambient CO2pressure and mild temperature. This report also provides the first proof-of-principle for the single-operation synthesis of elusive seven-membered ring cyclic urethanes.

DBU and DBU-Derived Ionic Liquid Synergistic Catalysts for the Conversion of Carbon Dioxide/Carbon Disulfide to 3-Aryl-2-oxazolidinones/[1,3]Dithiolan-2-ylidenephenyl- Amine

An intermolecular synergistic catalytic combination of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and a DBU-derived bromide ionic liquid has been developed for the conversion of CO2, epoxides, and amines under metal- And solvent-free conditions. Various 3-aryl-2-oxazolidinones are produced in moderate to excellent yields within a short reaction time. NMR spectroscopy and DFT calculations demonstrate that DBU as a hydrogen bond acceptor and the ionic liquid as a hydrogen bond donor activate the substrates cooperatively by inducing hydrogen bonds to promote the reaction effectively. Based on these results, a possible reaction mechanism on the synergistic catalysis of DBU and the ionic liquid is proposed. In addition, the reaction of CS2, ethylene oxide, and aniline catalyzed by the combination of DBU and the DBU-derived ionic liquid also proceeds smoothly, which opens a hitherto unreported route to [1,3]dithiolan-2-ylidenephenylamine in a straightforward way.

Bis-aryl urea derivatives as potent and selective LIM kinase (Limk) inhibitors

The discovery/optimization of bis-aryl ureas as Limk inhibitors to obtain high potency and selectivity and appropriate pharmacokinetic properties through systematic SAR studies is reported. Docking studies supported the observed SAR. Optimized Limk inhibitors had high biochemical potency (IC50 400-fold), potent inhibition of cofilin phosphorylation in A7r5, PC-3, and CEM-SS T cells (IC50 1 μM), and good in vitro and in vivo pharmacokinetic properties. In the profiling against a panel of 61 kinases, compound 18b at 1 μM inhibited only Limk1 and STK16 with ≥80% inhibition. Compounds 18b and 18f were highly efficient in inhibiting cell-invasion/migration in PC-3 cells. In addition, compound 18w was demonstrated to be effective on reducing intraocular pressure (IOP) on rat eyes. Taken together, these data demonstrated that we had developed a novel class of bis-aryl urea derived potent and selective Limk inhibitors.
