SYNTHESIS AND STRUCTURE OF E,Z-ISOMERIC FIVE-MEMBERED CYCLIC alpha-KETO-N-METHYL NITRONES

The respective E-isomeric nitrones were obtained by methylation of the monooximes of cyclic alpha-diketones.The photochemical transformation of five-membered cyclic E-alpha-keto-N-methyl nitrones into the thermodynamically less stable Z isomers was realized for the first time, and the conditions for the preparative realization of the process were determined.Detailed investigation of the IR, UV, PMR and 13C NMR spectra and the dipole moments of the obtained nitrones showed that the dipole moments and PMR spectra are most suitable for determinig the configuration (E or Z).

The X-ray diffraction analysis of a crystalline structure of the new gamma-hydroxyamide 3a is reported, as well as that of the first example of a crystalline structure where a diphenylborinic ester forms a seven membered chelate, by a carbonyl coordination to boron (4). Structural studies of tin and boron esters were performed by NMR. The C{double bond, long}O internal coordination to tin atoms, affording seven membered rings, was observed by 119Sn NMR experiments at low temperature.

Characterization of volatile components in four vegetable oils by headspace two-dimensional comprehensive chromatography time-of-flight mass spectrometry

Edible oil adulteration is the biggest source of food fraud all over the world. Since characteristic aroma is an important quality criterion for edible oils, we analyzed volatile organic compounds (VOCs) in four edible vegetable oils (soybean, peanut, rapeseed, and sunflower seed oils) by headspace comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (Headspace-GC×GC-TOFMS) in this study. After qualitative and quantitative analysis of VOCs, we used unsupervised (PCA) and supervised (Random forests) multivariate statistical methods to build a classification model for the four edible oils. The results indicated that the four edible oils had their own characteristic VOCs, which could be used as markers to completely classify these four edible oils into four groups.
