Reactions with acetone so...

Cerium(IV) ammonium nitrate was found to be a versatile reagent for the oxidative functionalization of styrenes using N-hydroxyphthalimide and iodine affording three different types of products with oxyphthalimide, nitrate and iodide groups. It was shown that reaction of styrenes with N-hydroxyp...

A polyiodide complex has been newly obtained during the cathodic oxidation of iodide ions (I−) in the presence of propylene carbonate (PC). This complex demonstrates features of both ionicity and hydrophobicity. The properties and structure of this complex were investigated and discussed in the ...

Formation of styrene carbonate (SC) by the cycloaddition of CO2 to styrene oxide (SO) catalysed by pyrrolidinopyridinium iodide (PPI) in combination with zinc halides (ZnCl2, ZnBr2 and ZnI2) was investigated. Complete conversion of the SO to SC was achieved in 3 h with 100% selectivity using 1/0...

Fructose 1,6-diphosphate (FDP) is a widely used medicine and is also a precursor of two important three-carbon phosphates – glyceraldehyde 3-phosphate (GA3P) and dihydroxyacetone phosphate (DHAP) for the biosynthesis of numerous fine chemicals. An in vitro synthetic cofactor-free enzymatic path...

In the design of inhibitors of phosphosugar metabolizing enzymes and receptors with therapeutic interest, malonate has been reported in a number of cases as a good and hydrolytically-stable surrogate of the phosphate group, since both functions are dianionic at physiological pH and of comparable...

Optically pure L-armentomycin [(S)-2-amino-4,4-dichlorobutanoic acid] and its D-isomer [(R)-2-amino-4,4-dichlorobutanoic acid] were prepared by using methyl (E)- and (Z)-2,4,4-trichloro-2-butenoate as key intermediate, which were reduced with baker's yeast to (R)- and (S)-2,4,4-trichlorobut...

The combination regimen of irinotecan (IRI) and doxorubicin (DOX) for cancer treatment has been frequently exploited in clinical studies, but face challenges in design of efficacious combination drug delivery systems. Here we demonstrate a novel nanoliposome constructed by triethylammonium sucro...

Neutral dinuclear Zn(II) phosphates [Zn2(L)2(phen)2(H2O)2], (L = L2; (1)), anionic dinuclear Zn(II)-phosphates [Et3NH]+[Zn2(L1)4(pyz)2]- (2) and tetranuclear double-4-ring (D4R) Zn(II) phosphates [Zn4(L)4(DMF)4] (5-7), (L = L1; (3), L3; (4), L4; (5)), [Zn4(L1)4(pyz)2(DMF)2] (6) and [Zn4(L4)4(phe...

The significant considerations have centred on the utilization of the bio-ionic liquids as green solvents to replace or minimize conventional environment-harming organic solvents. Ionic liquids have many remarkable environment-accepting properties such as ease of reuse, low vapour pressure, and ...

Since 2003, the authors have been pushing the boundaries on a special type of functional material, i.e., a material that gives off light when it is stressed, strained, and/or fractured. This unique class of materials has been proposed for the active element of impact sensors, earthquake detector...

The effect of the metal particle size and the modifier concentration on the enantioselectivity (ee) and the conversion level in the hydrogenation of three different substrates: 1-phenyl-1,2-propanedione, ethyl pyruvate and acetophenone were studied over Ir/SiO2 catalysts. The metal loading was v...

This paper focuses on the extraction of sclareol from the leaves of Salvia sclarea Lamiaceae, more commonly known as Clary sage. The process involves the extraction of sclareol using a CO2-soluble GRAS solvent such as ethyl lactate, followed by GAS anti-solvent precipitation from ethyl lactate s...

Different forms of biocatalysts (baker’s yeasts) were applied for the kinetic resolution of ethyl ester of 1-hydroxy-1-(3,4-dimethoxyphenyl)-methane(P-phenyl)phosphinic acid via enantioselective oxidation of hydroxyl-functionality. Stereochemistry of the reaction was modulated by the bioconvers...

This study aims to investigate the impacts of ethyl lactate (EL) based Fenton treatment on soil quality for polycyclic aromatic hydrocarbons (PAHs)-contaminated soils. Accumulation of oxygenated-polycyclic aromatic hydrocarbons (oxy-PAHs) was observed, but quantitative measurement on the most ab...

This work explores the potential for the development of a hybrid fermentation–enzymatic process for the production of ethyl lactate from dairy waste. Cheese whey was used in Kluyveromyces marxianus and Lactobacillus bulgaricus batch cultures to produce ethanol and lactic acid respectively. Subs...

In this paper, the potential application of non-toxic agrochemical solvent—ethyl lactate, to recover α-tocopherol from olive oil is studied. The work is based on experimental and modeling studies of the liquid–liquid equilibria at ambient pressure of three model systems: (i) binary (olive oil...

This study explores the potential for enhancing the production of ethyl lactate (EL), a green solvent, through enzymatic esterification. Different solvents were compared as organic media for conversion of lactate and ethanol into EL, catalyzed by Novozym 435. Chloroform and hexane were the most ...

The Lewis-acidity of a series of bis-cationic Pt(II)(aqua) complexes bearing phosphane ligands was exploited to catalyze the conversion of dihydroxyacetone to ethyl lactate. The Pt(II) complex bearing 1,2-bis(diphenylphosphanyl)ethane and triflate as counter anion showed high catalytic activity ...

Two Ho(C6H13NO)3(NO3)3 complexes formed by holmium nitrate and N-tert-butylacetamide (NtBA) (Ho-NtBA(I) in a Cc space group, and Ho-NtBA(II) in a P21/c space group) are reported here to investigate the coordination of lanthanide ions with amide groups. Using X-ray single crystal diffraction, FTI...
