Synthesis of 3-methylthio-4-aryl-3-pyrroline-2,5-diones and 3-arylpyrolidine-2,5-diones by reaction of nitroketene dithioacetal with arylacetonitriles

The reaction of nitroketene dithioacetal (1a), i.e., 2,2-bis(methylthio)-1-nitroethylene, with arylacetonitriles (2a-I) in the presence of the base like sodium hydroxide gave 4-nitrobut-2-enenitriles (3a-I) which were converted into 5-hydroxyimino-4-methylthio-3-phenyl-3-pyrrolin-2-ones (4a-i) under refluxing in methanol. Title compounds (5a-i) were readily obtained by the treatment of 4a-i with hydrochloric acid and were finally led to N-methylated products (6a-I) with methyl iodide. The reduction of maleimides (4-6) with zinc dust in acetic acid afforded the corresponding 3-arylpyrrolidine-2,5-diones (7a-i) that can be converted to pharmacologycally active compounds like mesembrines.

Research Progress on [3+n](n >= 3) cycloaddition of 1,3-Diploes

Versatile heterocyclic skeletons extensively exist in structures of natural products, drug molecules and organic materials, and have been synthesized through various strategies reported in literatures. Among them, the 1,3-dipolar cycloaddition is the most impressive class to build the related heterocycles. In the past, organic chemists generally employed [3+2] cycloaddition of 1,3-dipoles to assemble five-membered rings. As modern chemistry developes, researchers further turn their attention to the [3+3], [3+4], [3+5] and [3+6] cycloadditions, to construct six-, seven-, eight- and bridge-heterocyclic compounds. At present, review articles with topics on 1,3-dipolar cycloaddition mainly focus on [3+2] cycloaddition. Herein, A topic on [3 + n] (n >= 3) cycloaddition of 1,3-dipoles, with comments on the developed methodologies is present and the out-look in this field is proposed.

Can Medical-Grade Gloves Provide Protection after Repeated Disinfection?

The advent of the COVID-19 pandemic has generated an increased consumption of personal protective equipment (PPE), including gloves and masks, by healthcare workers and by the general public at a global scale. This has generated substantial shortage of these single-use and disposable PPEs that will end up as a landfill waste. Extending the life cycle of PPEs, such as gloves, by disinfecting treatments could help mitigate these concerns. However, the effect of various disinfection treatments on the functionality of gloves is unknown. In this study, six commonly used viral disinfection treatment methods (i.e., ultraviolet (UV) radiation, dry heat, steam, alcohol, chlorine compounds, and quaternary ammonium compounds) were evaluated for their effect on the performance attributes of two commonly used medical-grade gloves and nitrile and vinyl (latex) gloves. The barrier properties of both gloves against water and ethanol vapor flux were not affected up to 10 cycles of disinfection cycles. However, the increase in the disinfection cycle from 10 to 20 slightly reduced their barrier properties with minor variation in the type of disinfection and glove type. Infrared spectroscopy and microscopy investigations confirmed that both types of gloves could withstand up to 20 cycles of disinfection treatments with no observable change in the chemical structure and surface morphology of the disinfected surfaces, respectively. Lastly, tear property testing of the gloves indicated little to no change from the baseline after 20 cycles of treatment in both the nitrile and vinyl-based gloves. Overall, this study indicated that alcohol, UV, and heat treatment could be acceptable disinfection methods that allow the reuse of gloves up to 20 cycles. Such repeated disinfection of gloves not only reduces the strain on the supply of gloves but also decreases the postconsumer landfilled waste and environmental footprint of gloves.

Characterization of amino acid on glutathione adducts of cis-2-butene-1,4-dial, a reactive metabolite of furan

Metabolic activation of the hepatocarcinogen furan yields metabolites that react covalently with proteins, cis-2-Butene-1,4-dial is a microsomal metabolite of furan, This reactive aldehyde is thought to be the toxic metabolite that is responsible for the carcinogenic activity of furan. In order to characterize the chemistry by which this unsaturated dialdehyde could alkylate proteins, the products formed upon reaction of cis-2-butene-1,4-dial with model nucleophiles in PH 7.4 buffer were investigated, N-alpha-Acetyl-L-cysteine (AcCys) reacts with cis-2-butene-1,4-dial to form N-substituted pyrrolin-2-one adducts. N-Acetyl-L-cysteine (AcCys) reacts rapidly with cis-2-butene-1,4-dial to form multiple uncharacterized products. The inclusion of AcLys in this reaction mixture yielded an N-substituted 3-(S-acetylcysteinyl)pyrrole adduct which Links the two amino acid residues. Related compounds were isolated when cis-2-butene-1,4-dial and glutathione (GSH) were combined. In this case, cis-2-butene-1,4-dial cross-linked two molecules of GSH resulting in either cyclic or acyclic adducts depending on the relative GSH concentration. Incubation of furan with rat liver microsomes in the presence of [glycine-2-H-3]GSH led to the formation of radioactive peaks that coeluted with synthetic standards for the bisgluthathione conjugates. These studies demonstrate that the reactive cis-2-butene-1,4-dial formed during the microsomal oxidation of furan reacts rapidly and completely with amino acid residues to farm pyrrole and pyrrolin-2-one derivatives. Therefore, this metabolite is a likely candidate for the activated furan derivative that binds to proteins. The ease with which cis-2-butene-1,4-dial cross-links amino acids suggests that pyrrole-thiol cross-links may be involved in the toxicity observed following furan exposure.

Palladium-PEPPSI-NHC Complexes Bearing Imidazolidin-2-Ylidene Ligand: Efficient Precatalysts for the Direct C5-Arylation of N-Methylpyrrole-2-Carboxaldehyde

The Pd-catalyzed direct arylation of pyrroles is an important research field for organic synthesis and catalysis chemistry. However, imidazolidin-2-ylidene based Pd-NHC complexes (NHC=N-heterocyclic carbene) have not yet been employed as catalysts for the direct C5 mono-arylation of C2-substituted N-methylpyrrole derivatives with aryl halides. Therefore, we now report the synthesis and characterization of new 1,3-bis(substituted benzyl) imidazolinium salts as carbene precursors, and their corresponding Pd-PEPPSI-NHC type complexes (PEPPSI=Pyridine Enhanced Precatalyst Preparation Stabilization and Initiation). The catalytic properties of these complexes have been evaluated in the direct C5 mono-arylation of N-methylpyrrole-2-carboxaldehyde with a wide variety of (hetero)aryl halides. This environmentally attractive procedure has also been found to be tolerant to a wide variety of functional groups on the aryl halides such as formyl, acetyl, nitrile, fluoro or trifluoromethyl, and good yields have been obtained in presence of 1 mol% catalyst loading at 120 degrees C.

Clean and molecularly programmable protocol for preparation of bis-heterobiarylic systems via a domino pseudocyclic reaction as a valuable alternative for TM-catalyzed cross-couplings

The domino sequence of pseudocyclic reactions involving 4-methoxybenzonitrile N-oxide and trans-2-phenyl-1-cyano-1-nitroethene proceeding in mild (r.t.; atm. pressure) non-catalytic (without participation of palladium or other transition metals (TM)) conditions yielded a bis-heterobiarylic molecular system containing an oxadiazole moiety with an almost 40% yield. The presented methodology represents therefore an evident contrast to the existing methods of preparation of bis-heterobiarylic systems, which require the presence of TMs. This reaction should be considered stereochemically clean and contains a stage of cycloaddition to the C=N bond. It should be underlined that this is the first case of non-catalyzed [3 + 2] cycloaddition involving the nitrile C=N bond. Our comprehensive study shows that the described protocol can be applied as a general methodology for preparation of a wide group of bis-heterobiarylic molecules. The self-adjusted cascade of transformations, which is unique and valuable from the practical point of view, leads to formation of a single isomeric product (from many possible) as a consequence of three pseudocyclic tandem reactions performed in agreement with the fundamental principles of green chemistry and sustainable development with a maximal level of atom economy and good overall yields. A self-adjustment phenomenon observed in the studied smart technology leading to production of a material with special properties was explained by it deep quantum nature confirmed undoubtedly by the modern Molecular Electron Density Theory.
