Schuhmacher, Anne published the artcileCatalytic Synthesis of Potassium Acyltrifluoroborates (KATs) from Boronic Acids and the Thioimidate KAT Transfer Reagent, Product Details of C2H6N2O, the main research area is potassium acyltrifluoroborate preparation; boronic acid thioimidate transfer reagent cross coupling palladium catalyst; acylboron compounds; boronic acids; cross-coupling; synthetic methods; zwitterions.

We report the synthesis of potassium acyltrifluoroborates (KATs) by a palladium-catalyzed cross-coupling of boronic acids and the thioimidate KAT transfer reagent. The combination of widely available aryl- and vinylboronic acids with com. available thioimidate using catalytic PdII and a CuII additive enables the preparation of KATs in high yields and with good functional group tolerance. This formal insertion of CO into organoboronic acids can also be applied to boronic acid pinacol esters and potassium organotrifluoroborates using a slightly modified procedure. The cross-coupling can be telescoped into the one-pot synthesis of amides and α-aminotrifluoroborates by exploiting the unique chem. of KATs and their trifluoroborate iminium (TIM) derivatives

Pokluda, Adam published the artcileRobust Photocatalytic Method Using Ethylene-Bridged Flavinium Salts for the Aerobic Oxidation of Unactivated Benzylic Substrates, Formula: C2H6N2O, the main research area is ethylene bridged flavinium salt photoredox catalyst preparation fluorescence; benzyl ethylene bridged flavinium salt photocatalyst aerobic oxidation; aryl ketone preparation.

A series of ethylene-bridged flavinium salts I (R1, R2 = H, OMe, CF3, Cl; R1R2 = OCH2O; R3 = H, Me, n-octyl) has been synthesized and their photochem. and electrochem. properties have been studied. Out of these compounds, 7,8-dimethoxy-3-methyl-1,10-ethylenealloxazinium chloride I [R1 = R2 = MeO; R3 = Me; (II)] was found to be a superior photooxidation catalyst. The flavinium salt II proved to be robust enough for practical applications in benzylic oxidations/oxygenations, which was demonstrated using a series of substrates with high oxidation potential, i.e., 1-phenylethanol, ethylbenzene, diphenylmethane and diphenylmethanol derivatives substituted with electron-withdrawing groups (Cl or CF3). The unique capabilities of the compound II can be attributed to its high photostability and participation via a relatively long-lived singlet excited state, which was confirmed using spectroscopic studies, electrochem. measurements and TD-DFT calculations This allows the maximum use of the oxidation power of the compound II, which was given by its singlet excited state reduction potential of +2.4 V. This compound can be used as an alternative photocatalyst for even more difficult substrates.

Komar, Mario published the artcileApplication of Deep Eutectic Solvents in the Synthesis of Substituted 2-Mercaptoquinazolin-4(3H)-Ones: A Comparison of Selected Green Chemistry Methods, Application of 1-Methylurea, the main research area is mercaptoquinazolinone green preparation; anthranilic acid isothiocyanate microwave ultrasound choline chloride urea catalyst; 2-mercaptoquinazolin-4(3H)-one; deep eutectic solvents; green chemistry; microwave-assisted synthesis; ultrasound-assisted synthesis.

In this study, deep eutectic solvents (DESs) were used as green and eco-friendly media for the synthesis of substituted 2-mercaptoquinazolin-4(3H)-ones I [R1 = H, 6-I, 6-Br, 7-Cl, 6,8-dichloro; R2 = Me, Ph, Bn, etc.] from different anthranilic acids and aliphatic or aromatic isothiocyanates. A model reaction on anthranilic acid and Ph isothiocyanate was performed in 20 choline chloride-based DESs at 80 °C to find the best solvent. Based on the product yield, choline chloride:urea (1:2) DES was found to be the most effective, while DESs acted both as solvents and catalysts. Desired compounds were prepared with moderate to good yields using stirring, microwave-assisted, and ultrasound-assisted synthesis. Significantly higher yields were obtained with mixing and ultrasonication (16-76%), while microwave-induced synthesis showed lower effectiveness (13-49%). The structures of the synthesized compounds were confirmed by 1H and 13C NMR spectroscopy.

Blum, Stephan P. published the artcileMetal-Free Electrochemical Synthesis of Sulfonamides Directly from (Hetero)arenes, SO2, and Amines, COA of Formula: C2H6N2O, the main research area is sulfonamide dehydrogenative electrochem synthesis heteroarene amine; electrochemistry; green chemistry; oxidation; radical reactions; sulfonamides.

Sulfonamides are among the most important chem. motifs in pharmaceuticals and agrochems. However, there is no methodol. to directly introduce the sulfonamide group to a non-prefunctionalized aromatic compound Herein, we present the first dehydrogenative electrochem. sulfonamide synthesis protocol by exploiting the inherent reactivity of (hetero)arenes in a highly convergent reaction with SO2 and amines via amidosulfinate intermediate. The amidosulfinate serves a dual role as reactant and supporting electrolyte. Direct anodic oxidation of the aromatic compound triggers the reaction, followed by nucleophilic attack of the amidosulfinate. Boron-doped diamond (BDD) electrodes and a HFIP-MeCN solvent mixture enable selective formation of the sulfonamides. In total, 36 examples are demonstrated with yields up to 85%.

3,4-Dihydropyrimidin-2-ones (DHPMs) I [R1 = Ph, 3-HOC6H4, 2-O2NC6H4, etc.; R2 = Me, Et, i-Pr; R3 = H, Me] were synthesized by reaction of aromatic aldehydes, β-ketoester and urea/N-Me urea. These compounds I on oxidation with quinolinium chlorochromate as an oxidizing agent resulted into pyrimidin-2-ones II. The synthesized compounds I and II were screened against three test fungi of wheat crop, i.e., Alternaria triticina, Bipolaris sorokiniana and Ustilago segetum tritici by spore germination method. Compounds II showed excellent antifungal activity than compounds I with least ED50 values 42, 93 and 47 μg/mL. Among the tested compounds, compounds II [R1 = 4-O2NC6H4, R2 = i-Pr, R3 = H; R1 = 2,4-di-MeOC6H3, R2 = Et, R3 = Me] were found to be most active. Structure activity relationship showed that electron withdrawing group enhanced their efficacy due to +I effect and vice versa, whereas dehydrogenation improved their potential due to resonance stabilization of structures involved during electronic interactions between proteins of fungus cells and compounds

Bian, Yinghui published the artcileUnderstanding the oxidation and reduction reactions of sulfur in rechargeable aluminum-sulfur batteries with deep eutectic solvent and ionic liquid electrolytes, Application In Synthesis of 598-50-5, the main research area is aluminum sulfur secondary battery deep eutectic solvent; ionic liquid electrolyte; aluminum-sulfur batteries; deep eutectic solvents; electrolytes; ionic liquids; oxidation.

Al-based batteries are promising next-generation rechargeable batteries owing to the abundance of raw materials and their high potential energy d. The Al-S system has attracted considerable attention because of its high energy d. and low cost. However, its low discharge voltage plateau (0.6-1.2 V) hampers its practical application. Herein, eight ionic liquids or deep eutectic solvents were studied as electrolyte candidates for an Al-S cell. This was the first study to demonstrate that an Al-S cell based on an AlCl3/acetamide electrolyte (1.3 molar ratio) showed high discharge voltage plateaus (1.65-1.95 V) and a charging cut-off voltage of 2.5 V in Al-S cells. An Al-S cell of 0.33 mAh capacity with the AlCl3/acetamide electrolyte successfully lit up a red LED (forward voltage 1.6-2.0 V) for around 2 h. This work may help in promoting the development of high-performance and low-cost Al-S cells.

Ejaz, Iqra published the artcileRational design, synthesis, antiproliferative activity against MCF-7, MDA-MB-231 cells, estrogen receptors binding affinity, and computational study of indenopyrimidine-2,5-dione analogs for the treatment of breast cancer, Name: 1-Methylurea, the main research area is breast cancer antiproliferative estrogen receptor indenopyrimidine dione therapeutics; Breast cancer; Estrogen receptor (ER); MCF-7 cancer cells, Antiangiogenesis; Tricyclic indenopyrimidine-2,5-dione.

Based on the structural architecture of estrogen receptors (ER) agonists/antagonists, we rationally designed and synthesized indenopyrimidine-2,5-dione analogs as a starting point of current research targeting estrogen receptors. These analogs were evaluated for their antiproliferative activities against breast cancer MCF-7 (ER+), MDA-MB-231 (ER-) and non-cancerous HEK-293 cells using MTT assay. Compounds with high antiproliferative activity against MCF-7 breast cancer cells were found devoid of cytotoxicity against HEK-293 cells. Competitive binding assay of estrogen receptors ERα and ERβ showed that diethanolamine derivative of 4-trifluoromethyl Ph derivative 30 displayed 77.5-fold strong binding affinity towards ERα (IC50 = 0.004 μM) as compared to ERβ (IC50 = 0.31 μM). The calculated RBA value of compound 30 indicated that it has greater affinity with ER than estradiol. By docking studies, we demonstrated that high binding affinity with ERα is due to binding orientation and interaction of CF3 with a number of key amino acid residues present in the active site of ERα.

Pretze, Marc published the artcileSynthesis, radiolabelling and initial biological characterisation of 18F-labelled xanthine derivatives for PET imaging of Eph receptors, Safety of 1-Methylurea, the main research area is fluorine 18 xanthine derivative preparation imaging Eph receptor cancer.

Eph receptor tyrosine kinases, particularly EphA2 and EphB4, represent promising candidates for mol. imaging due to their essential role in cancer progression and therapy resistance. Xanthine derivatives were identified to be potent Eph receptor inhibitors with IC50 values in the low nanomolar range (1-40 nm). These compounds occupy the hydrophobic pocket of the ATP-binding site in the kinase domain. Based on lead compound 1, we designed two fluorine-18-labeled receptor tyrosine kinase inhibitors ([18F]2/3) as potential tracers for positron emission tomog. (PET). Docking into the ATP-binding site allowed us to find the best position for radiolabelling. The replacement of the Me group at the uracil residue ([18F]3) rather than the Me group of the phenoxy moiety ([18F]2) by a fluoropropyl group was predicted to preserve the affinity of the lead compound 1. Herein, we point out a synthesis route to [18F]2 and [18F]3 and the resp. tosylate precursors as well as a labeling procedure to insert fluorine-18. After radiolabelling, both radiotracers were obtained in approx. 5% radiochem. yield with high radiochem. purity (>98%) and a molar activity of >10 GBq μmol-1. In line with the docking studies, first cell experiments revealed specific, time-dependent binding and uptake of [18F]3 to EphA2 and EphB4-overexpressing A375 human melanoma cells, whereas [18F]2 did not accumulate at these cells. Since both tracers [18F]3 and [18F]2 are stable in rat blood, the novel radiotracers might be suitable for in vivo mol. imaging of Eph receptors with PET.
