Abstract A highly anti ‐selective asymmetric Henry reaction has been developed, affording synthetically versatile β‐nitroalcohols in a predominately manner (mostly above 15:1) and excellent ee values 95 %). Moreover, the was carried out presence of water for first time with up to 99 % . The catalytic mechanism proposed based on detection intermediates by extractive electrospray ionization mass spectrometry (EESI‐MS). Furthermore, adducts have successfully transformed into biochemically...
By using silver cations (Ag⁺) as the ionic reagent in reactive extractive electrospray ionization mass spectrometry (EESI-MS), concentrations of acetonitrile exhaled breath samples from volunteers including active smokers, passive and non-smokers were quantitatively measured vivo, without any sample pretreatment. A limit detection (LOD) relative standard deviation (RSD) 0.16 ng/L 3.5% (n = 8), respectively, for signals MS/MS experiments. Interestingly, human continuously increased 1-4 hours...
Abstract Exhaled nitric oxide (eNO) is a useful biomarker of various physiological conditions, including asthma and other pulmonary diseases. Herein fast sensitive analytical method has been developed for the quantitative detection eNO based on extractive electrospray ionization mass spectrometry (EESI-MS). NO molecules selectively reacted with 2-phenyl-4, 4, 5, 5-tetramethylimidazoline-1-oxyl-3-oxide (PTIO) reagent concentration was derived EESI-MS response 1-oxyl-2-phenyl-4,...
β-casein, a protein in milk and dairy products, has two main variant forms termed as A1 A2. β-casein may have adverse effects on humans. The fact that there is only one amino acid variation at the 67th position between A2 makes it difficult to distinguish them. In this study, novel method using characteristic thermolytic peptides developed for determination of milk. Firstly, caseins extracted from samples are digested 60 °C without any denaturing reagents required unfolding proteins, which...
The investigation of the metabolic toxicity nano- and microplastics is great significance in assessing their potential impacts on ecosystems human health, as it provides a fundamental scientific basis for environmental protection sustainable development. In this study, home-made internal extractive electrospray ionization source (iEESI) with advantages selective extraction no sample pretreatment was integrated high-resolution Orbitrap Fusion Tribrid mass spectrometer to investigate...
Sulfur hexafluoride (SF6), which survives in the atmosphere for an extremely long period of time, is most potent greenhouse gas regulated under Kyoto Protocol. So, accurate monitoring atmospheric SF6 plays important role study control policies reducing emissions. The instruments measurement are typically calibrated using certified reference materials. concentrations commercially available materials usually have a broad range, from 1 μmol/mol to 6000 μmol/mol. Some characteristics including...
Abstract In course of this study the reaction is also conducted in water for first time.
