3-Alkenyl-2-oxindoles: Synthesis, antiproliferative and antiviral properties against SARS-CoV-2

Sets of 3-alkenyl-2-oxindoles (6,10,13) were synthesized in a facile synthetic pathway through acid dehydration (EtOH/HCl) of the corresponding 3-hydroxy-2-oxoindolines (5,9,12). Single crystal (10a,c) and powder (12a,26f) X-ray studies supported the stru

Synthesis, biological evaluation and molecular docking of new sulfonamide-based indolinone derivatives as multitargeted kinase inhibitors against leukemia

Series of novel sulfonamide-based 3-indolinones 3a-m and 4a-f were designed, synthesized and then their cytotoxic activity was evaluated against a panel of sixty cancer cell lines. This screening indicated that 4-(2-(5-fluoro-2-oxoindolin-3-ylidene)acetyl)phenyl benzenesulfonate (4f) possessed promising cytotoxicity against CCRF-CEM and SR leukemia cell lines with IC50 values 6.84 and 2.97 μM, respectively. Further investigation of the leukemic cytotoxicity of compound 4f was carried out by performing PDGFRα, VEGFR2, Aurora A/B and FLT3 enzyme assays and CCRF-CEM and SR cell cycle analysis. These investigations showed that compound 4f exhibited pronounced dual inhibition of both kinases PDGFRα and Aurora A with potency of 24.15 and 11.83 nM, respectively. The in vitro results were supported by molecular docking studies in order to explore its binding affinity and its key amino acids interactions. This work represents compound 4f as a promising anticancer agent against leukemia.

Phosphorylation of Alkenyl and Aryl C-O Bonds via Photoredox/Nickel Dual Catalysis

A phosphorylation of alkenyl and aryl C-O bonds at room temperature via photoredox/nickel dual catalysis is reported. By starting from easily available and inexpensive sulfonates, a variety of important alkenyl phosphonates and aryl phosphine oxides are g

Chromatography-Free and Eco-Friendly Synthesis of Aryl Tosylates and Mesylates

Two chromatography-free and eco-friendly protocols have been developed to synthesize aryl tosylates and mesylates by the tosylation and mesylation of the corresponding hydroxyarenes, respectively. These protocols are superior to other known ones regarding

UREA COMPOUNDS AND THEIR USE AS FAAH ENZYME INHIBITORS

There is provided a compound having Formula I:(I) wherein: R1 is aryl which is optionally substituted with one or more groups selected from hydroxyl, halogen and C1-4 alkoxy, or R1 is aryl which is substituted with a second aryl group or an aryloxy group, wherein the second aryl group or the aryloxy group is optionally substituted with one or more groups selected from hydroxyl, halogen and C1-4 alkoxy; R2 is C1-4 alkyl; R3 is selected from hydroxyl and OSO2CH3; R4 and R5 are independently selected from hydrogen, hydroxyl and halogen; and n is 0 or 1; or a pharmaceutically acceptable salt thereof; wherein when R3 is hydroxyl and R4 and R5 are not hydroxyl, the optionally substituted aryl group, second aryl group or aryloxy group of R1 is substituted with one or more hydroxyl groups or C1-4 alkoxy groups, or wherein when R3 is hydroxyl, one of R4 and R5 is hydroxyl, provided that the compound is not N-(1-benzylpiperidin-4-yl)-4-(3,4-dihydroxyphenyl)-N-methyl-1H-imidazole-1-carboxamide hydrobromide. The compound may be used as an inhibitor of fatty acid amide hydrolase.

Comparative Study of the Limitations and Challenges in Atom-Transfer C-H Oxidations

A comparative study is disclosed that seeks to highlight the current limitations and challenges that exist in the field of atom-transfer C-H oxidations. State-of-the-art methods are benchmarked in order to showcase clear differences and similarities. A novel Mn-mediated method for C-H oxidation is disclosed that serves as a rapid and simple method for aliphatic C-H hydroxylation. Finally, two methods that allow for C-H oxidation in the presence of pyridine-containing substrates are studied, something that is rare in the field but of great interest to the chemical community.

Cyanation of unactivated aryl chlorides and aryl mesylates catalyzed by palladium and hemilabile MOP-type ligands

Palladium-catalyzed cyanation of aryl halides and pseudo halides with potassium hexacyanoferrate is described employing the hemilabile, bulky, and electron-rich MOP-type ligands. When the mixture of t-BuOH and H2O was used as the solvent and K2CO3 as the base, the MOP-type ligands showed high efficiency for the palladium-catalyzed cyanation. The effect of ligand structure was studied in detail, and 2-di-tert-butylphosphino-2′-isopropoxy-1,1′-binaphthyl was the more effective for the cyanation. The catalyst system allows the cyanation of unactivated aryl chlorides, and even aryl mesylates to occur in good yields. Furthermore, the reactivity of different arylated reagents in the catalytic system was found to be: ArBr > ArCl >> ArOMs > ArOSO2Im > ArOSO2NMe2.

A general palladium catalyst system for suzuki-miyaura coupling of potassium aryltrifluoroborates and aryl mesylates

(Figure presented) The first general examples of palladium-catalyzed Suzuki-type cross-coupling of aryl and heteroaryl mesylates with potassium aryl and heteroaryltrifluoroborates are presented. In addition to biaryl couplings, the cross-coupling reactions of aryl mesylates with alkyl and vinyltrifluoroborate salts have also been successfully accomplished.

A mild and efficient palladium-catalyzed cyanation of aryl mesylates in water or tBuOH/water

Cool and compatible: Aryl mesylates and tosylates underwent palladium-catalyzed cyanation under mild, aqueous conditions at 65-80°C (see scheme). In many cases, water could be used as the reaction medium without a cosolvent, and a variety of substituents R, such as keto, aldehyde, ester, free amine, and nitrile groups, remained intact during the transformation. Cy=cyclohexyl, Ms=methanesulfonyl, Ts=p-toluenesulfonyl.
