Under metal- and ligand-free conditions, the economical and accessible CF3SO3H successfully catalyzed homogeneous O-H bond insertion reactions between hydroxyl compounds and diazo compounds. Including phenols, alcohols, water and oximes, these O-H bond insertion reactions are very general and functional-group tolerant. Here, we first report the O-H bond insertion of oximes (ketoximes and aldoximes), and their structures were characterized by X-ray crystallography. Moreover, a simple and effective method for S-H insertion reactions of thiols was also developed, delivering the desired C-S bond products with good to excellent yields. It is worth noting that the efficacy of the developed methodology could be further shown by the expeditious synthesis of the PPAR agonist MBX-102 acid.

Lignin from the Chinese quince (Chaenomeles sinensis) fruit offers a promising source of natural antioxidant for industrial applications. However, the utilization of Chinese quince fruit lignin is restricted by its inhomogeneous nature. Accordingly, Chinese quince fruit lignin was sequentially fractionated with organic solvents of increasing dissolving capacity to prepare homogeneous lignin fractions. The GPC (gel permeation chromatography) results showed that the molecular weights of lignin fractions increased from dichloromethane fraction to dioxane/water fraction. The five lignin fractions were also compared with respect to yield, carbohydrate content, thermal stability, inter-unit linkages, S/G ratios, and phenolic OH content. Among the five fractions, the ethyl acetate fraction showed a lower proportion of p-o-tv linkages (48.4%), the highest thermal stability, the highest phenolic OH content (2.8 mmol/g), and the highest DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging index and reducing power. The high antioxidant performance of the ethyl acetate fraction implies that it can be used as a natural antioxidant. This study shows that sequential solvent fractionation of lignin can produce homogeneous fractions with enhanced antioxidant performance. In addition, it demonstrates that Chinese quince fruits are a potentially valuable natural resource.

A novel series of 7,8-dichlorobenzofuro[3,2-c]quinoline-6,9,10(5H)-triones was obtained regioselectively in good yields. The products were formed by the reactions of the 4-hydroxy-2(1H)-quinolinones with 3,4,5,6-tetrachloro-1,2-benzoquinone in tetrahydrofuran as the solvent. Infrared, nuclear magnetic resonance (two-dimensional nuclear magnetic resonance), mass spectra and elemental analysis were used to elucidate the structures of new compounds.

Product Details of 120-14-9. I found the field of Chemistry; Food Science & Technology very interesting. Saw the article Nutritional and chemical profiling of UK-grown potato bean (Apios americana Medik) reveal its potential for diet biodiversification and revalorisation published in 2021.0, Reprint Addresses Neacsu, M (corresponding author), Univ Aberdeen, Rowett Inst, Aberdeen AB25 2ZD, Scotland.. The CAS is 120-14-9. Through research, I have a further understanding and discovery of 3,4-Dimethoxybenzaldehyde.

Apios americana Medik, a native American plant has potential as a commercially viable Northern European-grown motcrop, mainly due to its resistance to extreme climate and nutritional quality. Analysis of A. americana sourced from two UK sites; South (51.4690 degrees N, 1.1150 degrees W) and North (55.9661 degrees N, 3.2063 degrees W) showed that the tubers were a complete source of amino acids (UPLC-TUV analysis), were rich in protein (15.0 +/- 0.0160 and 17.3 +/- 0.0779%; Vario Max CN analysis), fibre (total non-starch polysaccharides, 10.4 +/- 0.570 and 10.6 +/- 0.280%; GC analysis) and micronutrients (calcium, manganese, iron, zinc, molybdenum, potassium and phosphorus; ICP-MS analysis). Apios americana tubers were also rich in bioactive phytochemicals. From the 156 plant metabolites measured using LC-MS/MS analysis, genistein was the major phytophenol in both the Southern- and Northern UK tubers (259 +/- 12.2 mg Kg(-1) and 356 +/- 29.9 mg Kg(-1) respectively); the peel having similar phytochemical profiles. The protein and fibre content of the leaves (17.3 +/- 0.0434% and 11.7 0.0445%) and rhizomes (18.4 +/- 0.0152% and 13.5 +/- 0.590%) were significantly higher (p < 0.05) than the tubers. The leaves were also a good source of anthocyanins; delphinidin and cyanidin (840 +/- 137 and 3934 +/- 176 mg Kg(-1) respectively). Cultivation of A. americana as a high-protein staple-crop has enormous potential in Northern European countries for human nutrition, diet diversification, and use in livestock diets.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.
