NMR spectroscopic and theoretical evidence of cinchona alkaloid- ketopantolactone complex formation in aprotic solvents: Implications for the mechanism of Pt-catalyzed enantioselective hydrogenation of activated ketones

NMR spectroscopy (standard 2D NMR spectroscopic methods and diffusion-ordered NMR spectroscopy) and theoretical calculations (ab initio modeling at the density functional level and natural bond orbital analysis) were used to verify formation of supramolecular complexes between the pairs O-methylcinchonine-ketopantolactone (KPL) and beta-isocinchonine-KPL in deuterobenzene solution. The first direct evidence was found on the interaction of the lone pair of the quinuclidine N atom and the prochiral keto-carbonyl group of the KPL. Strong nN ? pi* interactions were observed between the nonbonding orbital of the quinuclidine N atom and the pi* antibonding orbitals of the C{double bond, long}O bonds. The complex was demonstrated experimentally to be stabilized not only by the H bonds between H 5? of the chiral modifier and the KPL, but also, depending on the structure of the cinchona alkaloid, by those between H8 and H9 and the KPL. In aprotic solvents, this type of experimentally verified adduct may be present on the Pt surface and participate in chiral induction in the Orito reaction.

Catalyst-Free Decarboxylation of Carboxylic Acids and Deoxygenation of Alcohols by Electro-Induced Radical Formation

Electro-induced reduction of redox active esters and N-phthalimidoyl oxalates derived from naturally abundant carboxylic acids and alcohols provides a sustainable and inexpensive approach to radical formation via undivided electrochemical cells. The resulting radicals are trapped by an electron-poor olefin or hydrogen atom source to furnish the Giese reaction or reductive decarboxylation products, respectively. A broad range of carboxylic acid (1, 2, and 3) and alcohol (2 and 3) derivatives are applicable in this catalyst-free reaction, which tolerated a diverse range of functional groups. This method features simple operation, is a sustainable platform, and has broad application.

Flavoromics approach in monitoring changes in volatile compounds of virgin rapeseed oil caused by seed roasting

Two varieties of rapeseed (one high oleic – containing 76% of oleic acid, and the other – containing 62% of oleic acid) were used to produce virgin (pressed) oil. The rapeseeds were roasted at different temperature/time combinations (at 140-180. C, and for 5-15. min); subsequently, oil was pressed from the roasted seeds. The roasting improved the flavour and contributed to a substantial increase in the amount of a potent antioxidant-canolol. The changes in volatile compounds related to roasting conditions were monitored using comprehensive gas chromatography-mass spectrometry (GC ¡Á GC-ToFMS), and the key odorants for the non-roasted and roasted seeds oils were determined by gas chromatography-olfactometry (GC-O). The most important compounds determining the flavour of oils obtained from the roasted seeds were dimethyl sulphide, dimethyltrisulfide, 2,3-diethyl-5-methylpyrazine, 2,3-butenedione, octanal, 3-isopropyl-2-methoxypyrazine and phenylacetaldehyde. For the oils obtained from the non-roasted seeds, the dominant compounds were dimethylsulfide, hexanal and octanal. Based on GC ¡Á GC-ToFMS and principal component analysis (PCA) of the data, several compounds were identified that were associated with roasting at the highest temperatures regardless of the rapeseed variety: these were, among others, methyl ketones (2-hexanone, 2-heptanone and 2-octanone).
