Bhat, Navya Subray published the artcileHydrochloric acid-catalyzed coproduction of furfural and 5-(chloromethyl)furfural assisted by a phase transfer catalyst, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Carbohydrate Research (2020), 108105, database is CAplus and MEDLINE.

Furfural has been produced in 53% isolated yield from D-xylose within an aqueous HCl-1,2-dichloroethane biphasic reaction mixture using benzyltributylammonium chloride (BTBAC) as a phase transfer catalyst. The use of BTBAC noticeably improved the yield of furfural compared to that in the control reaction. The reaction was optimized on the reaction temperature, duration, concentration of HCl, and the loading of BTBAC. Furfural and 5-(chloromethyl)furfural (CMF) have also been coproduced from a mixture of pentose and hexose sugars. Under optimized conditions (100°C, 3 h, 20.2% HCl, 10 wt% BTBAC), CMF and furfural were isolated in 17% and 53% yield, resp., from a mixture of glucose and xylose. In addition, levulinic acid was isolated from the aqueous layer in 31% yield.

Shi, Feng published the artcileSelective oxidation of naphthalene derivatives with ruthenium catalysts using hydrogen peroxide as terminal oxidant, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Molecular Catalysis A: Chemical (2007), 270(1-2), 68-75, database is CAplus.

The selective oxidation of naphthalene and its derivatives to give naphthoquinones has been investigated in detail. The reaction can be carried out effectively in the presence of a catalytic amount of Ru complexes (0.2 mol %) and phase transfer catalysts using H₂O₂ as the terminal oxidant and water as the solvent. The effects of different ruthenium complexes, phase transfer catalysts, and the concentration of hydrogen peroxide were studied. Compared to previous procedures for this type of reaction, acidic solvents and high concentration of hydrogen peroxide are not necessary, which makes the reaction more environmentally friendly.

Peltenburg, Hester published the artcileSorption of structurally different ionized pharmaceutical and illicit drugs to a mixed-mode coated microsampler, Quality Control of 23616-79-7, the publication is Journal of Chromatography A (2016), 1-8, database is CAplus and MEDLINE.

The mixed-mode (C18/strong cation exchange-SCX) solid-phase microextraction (SPME) fiber has recently been shown to have increased sensitivity for ionic compounds compared to more conventional sampler coatings such as polyacrylate and polydimethylsiloxane (PDMS). However, data for structurally diverse compounds to this (prototype) sampler coating are too limited to define its structural limitations. The authors determined C18/SCX fiber partitioning coefficients of nineteen cationic structures without hydrogen bonding capacity besides the charged group, stretching over a wide hydrophobicity range (including amphetamine, amitriptyline, promazine, chlorpromazine, triflupromazine, difenzoquat), and eight basic pharmaceutical and illicit drugs (pKa >8.86) with addnl. hydrogen bonding moieties (MDMA, atenolol, alprenolol, metoprolol, morphine, nicotine, tramadol, verapamil). In addition, sorption data for three neutral benzodiazepines (diazepam, temazepam, and oxazepam) and the anionic NSAID diclofenac were collected to determine the efficiency to sample non-basic drugs. All tested compounds showed nonlinear isotherms above 1 mmol/L coating, and linear isotherms below 1 mmol/L. The affinity for C18/SCX-SPME for tested organic cations without H-bond capacities increased with longer alkyl chains, ranging from logarithmic fiber-water distribution coefficients (log D_fw) of 1.8 (benzylamine) to 5.8 (triflupromazine). Amines smaller than benzylamine may thus have limited detection levels, while cationic surfactants with alkyl chain lengths >12 carbon atoms may sorb too strong to the C18/SCX sampler which hampers calibration of the fiber-water relationship in the linear range. The log D_fw for these simple cation structures closely correlates with the octanol-water partition coefficient of the neutral form (K_ow,N), and decreases with increased branching and presence of multiple aromatic rings. Oxygen moieties in organic cations decreased the affinity for C18/SCX-SPME. Log D_fw values of neutral benzodiazepines were an order of magnitude higher than their log K_ow,N. Results for anionic diclofenac species (log K_ow,N 4.5, pKa 4.0, log D_fw 2.9) indicate that the C18-SCX fiber might also be useful for sampling of organic anions. This data supports the authors’ theory that C18-based coatings are able to sorb ionized compounds through adsorption and demonstrates the applicability of C18-based SPME in the measurement of freely dissolved concentrations of a wide range of ionizable compounds

Jamal Ahamed, V. S. published the artcileRadical polymerization of methyl methacrylate (MMA) initiated by KHSO₅-BTBAC system – a kinetic study, Name: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Polymer Research (2012), 19(2), 1-8, database is CAplus.

Kinetics of free radical polymerization of Me methacrylate using potassium peroxomonosulfate as initiator in the presence of benzyltributylammonium chloride (BTBAC) as phase transfer catalyst was studied. The polymerization reactions were carried out under nitrogen atm. and unstirred conditions at a constant temperature of 60°C in Et acetate/water bi-phase system. The role of concentrations of monomer, initiator, catalyst, temperature, acid and ionic strength on the rate of polymerization (R_p) was ascertained. The orders with respect to monomer, initiator and phase transfer catalyst were found to be 1.5, 0.5 and 0.5 resp. The rate of polymerization (R_p) is independent of ionic strength and pH. Based on the kinetic results, a suitable mechanism is proposed.

Fushimi, Nobuhiko published the artcileDesign, synthesis, and structure-activity relationships of a series of 4-benzyl-5-isopropyl-1H-pyrazol-3-yl β-D-glycopyranosides substituted with novel hydrophilic groups as highly potent inhibitors of sodium glucose co-transporter 1 (SGLT1), Product Details of C19H34ClN, the publication is Bioorganic & Medicinal Chemistry (2013), 21(3), 748-765, database is CAplus and MEDLINE.

Sodium glucose co-transporter 1 (SGLT1) plays a dominant role in the absorption of glucose in the gut and is considered a promising target in the development of therapeutic options for postprandial hyperglycemia. Previously, we reported potent and selective SGLT1 inhibitors 1 and 2 showing efficacy in oral carbohydrate tolerance tests in diabetic rat models. In a pharmacokinetic (PK) study of glycoside I (R = OH), excessive systemic exposure to metabolites of I (R = OH) was observed, presumably due to the high permeability of its aglycon. To further improve SGLT1 inhibitory activity and reduce aglycon permeability, a series of 4-benzyl-5-isopropyl-1H-pyrazol-3-yl β-D-glycopyranoside derivatives, e.g. I (R = NH₂), bearing novel hydrophilic substitution groups on the Ph ring were synthesized and their inhibitory activity toward SGLTs was evaluated. Optimized compound II showed an improved profile satisfying both higher activity and lower permeability of its aglycon. Moreover, the superior efficacy of II in various carbohydrate tolerance tests in diabetic rat models was confirmed compared with acarbose, an α-glucosidase inhibitor (α-GI) widely used in the clinic.

Reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide with potassium salt of curcumin [bis-1,7-(3′-methoxy-4′-hydroxy)phenyl-5-hydroxy-1,4,6-heptatrien-3-one] under either thermal or high pressure conditions affect the labile substrate, curcumin, thus resulting in drastic reduction in the yields of the glucosides. This drawback could be effectively overcome by carrying out the biphasic reaction in the presence of a phase transfer catalyst under the effect of ultrasound. The reaction under the sonochem. conditions was faster and resulted in the increased yield of the glucoside products. The reaction was investigated in detail with a view to optimizing the yield of the glucosides. The detailed study clearly indicated the important role of the nature and quantity of the phase transfer catalyst employed in the reaction. Also, the selectivity with respect to the formation of mono- or di-β-glucosides under both mono- and biphasic reaction conditions was clearly discernable. The study establishes a simple synthetic protocol for the glucoside derivatives of curcumin in high yields and selectivity using ultrasonic waves.

Recycling of valuable metals from spent catalysts in a green way is gaining extensive interest for economic and environment reasons. In this study, we developed novel hydrophobic deep eutectic solvents to extract Mo from spent catalysts. The hydrophobic DESs have been designed and synthesized by mixing one molar of the quaternary ammonium salt and two molars of various saturated fatty acids with different carbon chain lengths. The extraction ability and extraction mechanism of these DESs were studied, some factors influencing the extraction efficiency, including the structure of hydrogen bond acceptors and hydrogen bond donors, initial aqueous pH, reaction time and temperature, phase ratios were investigated. It is found that the synthesized hydrophobic DESs exhibit excellent extraction performance toward Mo, where the Mo distribution ratio is more than 2200 in the presence of other metals, corresponding to an extraction efficiency of 99% at optimal reaction conditions. This work reveals a distinct class of materials, guiding an effective and green way for spent catalyst treatment. Implications: Novel hydrophobic deep eutectic solvents have been developed to extract Mo from spent catalysts, the synthesized hydrophobic DESs possess several advantages, such as green, low price, low toxicity, and biodegradability. It exhibits excellent extraction performance under an optimized extraction condition. This work reveals a distinct class of materials, guiding a promising way for green and economical utilization of spent catalysts.
