The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde.

A range of TsDPEN catalysts containing heterocyclic groups on the amine nitrogen atom were prepared and evaluated in the asymmetric transfer hydrogenation of ketones. Bidentate and tridentate ligands demonstrated a mutual exclusivity directly related to their function as catalysts. A broad series of ketones were reduced with these new catalysts, permitting the ready identification of an optimal catalyst for each substrate and revealing the subtle effects that changes to nearby donor groups can exhibit.

A photocatalyst-free stereoselectively photo-induced strategy for the denitroalkylation of beta-nitrostyrenes using 4-alkyl substituted Hantzsch esters as the alkyl source under xenon lamp irradiation is developed. The reaction proceeds at room temperature and affords the corresponding products in moderate to excellent yields. The oxidant di-t-butyl peroxide serves as an efficient radical initiator under irradiation of a Xenon lamp, initiating alkyl radicals from the 4-alkyl substituted Hantzsch esters.

Acridines and acridinium ions are one of the important classes of compounds in terms of their usefulness in pharmaceuticals, materials, dyes and photo-catalysis. Here we present an unconventional FeCl3-alcohol catalysed one-pot method for their synthesis directly from aldehydes, 1,3-cyclohexanedione and amines. This method efficiently merged high atom-economy and diversity of multicomponent reaction with novel iron catalyzed dehydrogenation, using aerobic oxygen as the terminal oxidant, in alcoholic solvent to produce water as the only by-product. Easy scaling up of the method has been successfully demonstrated.

A new protocol for the chemoselective aromatization of tetrahydro-beta-carboline-3-carboxylic acids to direct biomimetic one step synthesis of beta-carboline-3-carboxylic acids 2 A-L using catalytic amount of I-2 in DMSO/H+ produces very good yield. This method was also successfully extended for the aromatization of tetrahydro-beta-carboline-3-methyl esters 5 A-G as well as one-step synthesis of Marinacarbolines-D analog, respectively. Further, the mechanism and role of iodine-DMSO in aromatization has been studied by Density Functional Theory Calculation.

Novel task dicationic ionic liquids (Ts-DilLs) 6-29 were designed and synthesized, under both conventional and microwave conditions; through molecular hybridization of the appropriate bispyridines having a hydrazone linkage as spacer with some alkyl functionalized esters forming the counter cations. Beside the synthesized halogenated DilLs 6-11, fluorinated metal anions were introduced via metathesis reaction in order to create new dipyridinium ionic liquid-hydrazone hybrids 12-29. All newly synthesized DilLs were fully characterized using different spectroscopic tools such as H-1, C-13, F-19, P-31, B-11 NMR and Mass experiment. The DNA binding, anticancer and docking studies of the synthesized ionic liquids were also carried out. The DNA binding constants ranged from 4.5 x 10(4) to 7.2 x 10(4) M-1, indicating good DNA binding tendencies. The most active ionic liquids were 28 and 29 with 99.99 and 99.86% anticancer activities, respectively. The docking studies indicated DNA binding in the outer grooves of DNA. The reported ionic liquids may be used as future anticancer drugs. (C) 2020 Elsevier B.V. All rights reserved.

New sulfonamide-hydrazone derivatives (3a-3n) were synthesized to evaluate their inhibitory effects on purified human carbonic anhydrase (hCA) I and II. The inhibition profiles of the synthesized compounds on hCA I-II isoenzyme were investigated by comparing their IC50 and K-i values. Acetazolamide (5-acetamido-1,3,4-thia-diazole-2-sulfonamide, AZA) has also been used as a standard inhibitor. The compound 3e demonstrated the best hCA I inhibitory effect with a K-i value of 0.1676 +/- 0.017 mu M. Besides, the compound 3m showed the best hCA II inhibitory effect with a K-i value of 0.2880 +/- 0.080 mu M. Cytotoxicity of the compounds 3e and 3m toward NIH/3T3 mouse embryonic fibroblast cell line was observed and the compounds were found to be non-cytotoxic. Molecular docking studies were performed to investigate the interaction types between active compounds and hCA enzymes. Pharmacokinetic profiles of compounds were assessed by theoretical ADME predictions. As a result of this study a novel and potent class of CA inhibitors were identified with a good activity potential.

The anti-selective direct asymmetric Mannich reaction of (hetero) aromatic aldehydes, 4-anisidine and O-protected hydroxyacetones for the synthesis of stereodefined anti-beta-amino-alpha-hydroxycarbonyl compounds was developed. Protease type XIV from Streptomyces griseus (SGP) was used as a biocatalyst in 1,4-dioxane/phosphate buffer under mild reaction conditions. The excellent diastereoselectivities of up to >99:1 (anti/syn) and good enantioselectivities of up to 90% ee were achieved. This method provides a more sustainable complement to chemically catalyzed anti-selective direct asymmetric Mannich reactions. (C) 2019 Elsevier Ltd. All rights reserved.

Safety of 3-Pyridinecarboxaldehyde. I found the field of Chemistry; Engineering very interesting. Saw the article Design and synthesis of a versatile cooperative catalytic aerobic oxidation system with co-immobilization of palladium nanoparticles and laccase into the cavities of MCF published in 2020.0, Reprint Addresses Rostami, A (corresponding author), Univ Kurdistan, Fac Sci, Dept Chem, Sanandaj 6617715175, Iran.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde.

We have designed a versatile reusable cooperative catalyst oxidation system, consisting of palladium nanoparticles and laccase with unprecedented reactivity. This biohybrid catalyst was synthesized by the stepwise immobilization of laccase as an enzyme and Pd as a nanometallic component into the same cavity of siliceous mesocellular foams (MCF). MCF and nanobiohybrid catalyst were characterized by BET, SAXS, SEM, EDX elemental mapping, ICP-OES, TEM, TGA, FT-IR, and XPS techniques and the stepwise immobilization of laccase enzyme and Pd onto MCF was evaluated through several compelling electrochemical studies. The present catalytic system exhibits high activity toward (i) aerobic oxidation of alcohols to the corresponding carbonyl compounds, (ii) aerobic oxidation of cyclohexanol and cyclohexanone to phenol and (iii) aerobic dehydrogenation of important N-heteocyclic compounds (tetrahydro quinazolines, quinazolonones, pyrazolines and 1,4-diydropyridines) in the presence of catalytic amount of hydroquinone (HQ) as mediator in phosphate buffer (0.1 M, pH 4.5, 4 mL)/THF (4%, 1 mL) as solvent under mild conditions. The immobilization of both oxygen-activating catalyst (laccase) and oxidizing catalyst (Pd) onto the same support makes the present catalyst system superior to other currently available heterogeneous palladium based catalytic aerobic oxidation systems.
