Aza-Michael adducts are obtained in excellent yields by the conjugate addition of nucleophilic reagents with alpha,beta-unsaturated substrates such as methyl methacrylate (MMA), which were obtained from degradation poly(methyl methacrylate) plastic wastes using green energy source and were used as usuful precoursors for the synthesis of novel heterocycles, such as pyrazole, isochromene, quinolone, and amino isoxazole. Density functional theory (DFT) calculations at the B3LYP/6-311G level of theory have been carried out to investigate the stability of isochromene and quinolone. Moreover, HOMO and LUMO energy, total energy, and atomic Mulliken charges were calculated. The dipole moment and orientation of the two p-isoelectronic isochromene 15 and quinolone 20d have been also measured and their interactions with aromatic aldehydes to form isochromene 15 and quinolone 20d have been studied.

1008-75-9, Name is 3-Methyl-5-phenylisoxazole, belongs to isoxazole compound, is a common compound. Safety of 3-Methyl-5-phenylisoxazoleIn an article, once mentioned the new application about 1008-75-9.

4-rylisoxazoles can be easily prepared by a palladium-catalysed C-H bond activation/arylation of 3,5-disubstituted isoxazoles using aryl or heteroaryl bromides. Good yields were generally obtained by using 0.1-0.5 mol-% of the airstable PdCl2 complex as the catalyst. A range of functional groups such as acetyl, formyl, ester, fluoro, nitro, trifluoro-methyl or nitrile on the aryl bromide is tolerated. This reaction is environmentally attractive, as the major waste is KBr/ AcOH instead of the metallic salts arising from classical cross-coupling procedures,

Making use of computational approaches like virtual screening of compound libraries are essential steps in drug discovery mission. Several thousands of ligands and their analogs need to be computationally modeled and tested during early stages of drug discovery in order to identify the best molecule with desired characteristics against the target protein which causing the disease. Manual sketching of ligands and their analogs is a time consuming approach with high degree of human errors involved. eAnalogs is a novel computational algorithm to override the manual methods. eAnalogs is a fast, reliable web-accessible software for construction of automated ligand analog libraries. The algorithm is based on simple random sample statistical approach to create each analog of pre-defined atoms or functional groups with equal selection probability. The de novo ligand design tool helps medicinal chemists to rapidly and accurately generate hundreds of analogs from basic 2-dimensional chemical scaffold. The algorithm is capable of generating multiple analogs from single input chemical structure by adding user-defined atoms, functional groups and ring structures to the selected positions in a combinatorial manner. Software allows users to download result library in PDF and Structure Data Formats (SDF) that can be further used for processing virtual High Throughput Screening (vHTS), Quantitative Structure-Activity Relationship (QSAR), Lead Identification and Optimization techniques.

Based on the current economic and environmental analysis of the textile waste streams, textile waste alone can be a promising source of renewable energy. To realize that, catalyst-supported pyrolysis was used in the present research to treat textile waste and convert it into value-added energy carriers while attempting to minimize consumption of consumable chemicals (catalysts) and pyrolysis time and maximize the yield of valuable bio-oil and gases (Methane and Hydrogen). Pyrolysis was conducted on waste jeans (a major fraction of textile waste, rich in cellulose/cotton) with different dye colors (black and blue) and dye-originating heavy metals (used as a self-catalysts). Waste jeans of both colors were pyrolyzed in original condition and after acid leaching to remove the heavy metals for comparison. Also, the pyrolysis experiments were performed according to Technology Readiness Levels (TRL) concept, particularly in laboratory and pilot scale phases. At the first phase, Differential thermal analysis/Thermogravimetric analysis/3D-Fourier-Transform Infrared spectroscopy was employed to simulate the pyrolysis on a lab scale (fundamental level of TRL) and study the thermal and chemical decomposition of the selected samples up to 800 C. At the second stage, a pilot pyrolysis plant was built (based on the fundamental results received from lab scale) to simulate the industrial energy conversion conditions and obtain the data needed to apply the developed approach at industrial scale. The developed plant consisted of four units: pyrolysis reactor (capacity 300 g, Nitrogen ambient, and max. temp. 800 C), gas purification unit, instantaneous gas composition analysis unit (to study the effect of pyrolysis temperature on the generated Oxygen, Nitrogen, Carbon Monoxide, Carbon dioxide, Methane, and Hydrogen gases), and gas products collection unit. The pyrolysis products were analyzed using Gas Chromatography?Mass Spectrometry, Fourier-Transform Infrared Spectroscopy, elemental analysis, and Scanning Electron Microscope- Energy-dispersive X-ray Spectroscopy. The results showed that the developed technology successfully converted more than 82% of the feedstock into liquid-gas products and that the untreated feedstock had effective bio-oil yield 36?37.6% (depending on the composition of self-catalysts), which was ?20% higher compared to the treated batches; 18% reduction in pyrolysis time of untreated feedstock was achieved as well.

Theories about the origin of life require chemical pathways that allow formation of life?s key building blocks under prebiotically plausible conditions. Complex molecules like RNA must have originated from small molecules whose reactivity was guided by physico-chemical processes. RNA is constructed from purine and pyrimidine nucleosides, both of which are required for accurate information transfer, and thus Darwinian evolution. Separate pathways to purines and pyrimidines have been reported, but their concurrent syntheses remain a challenge. We report the synthesis of the pyrimidine nucleosides from small molecules and ribose, driven solely by wet-dry cycles. In the presence of phosphate-containing minerals, 5?-mono- and diphosphates also form selectively in one-pot reactions. The pathway is compatible with purine synthesis, allowing the concurrent formation of all Watson-Crick bases.
