In the paper there is considered the question of the influence of temperature on the course of the early stages of degradation D-glucose in aqueous solutions in pH range 1,0–7,0. By Raman spectroscopy there is demonstrated that within the temperature limi... see more

In the paper there is considered the question of the influence of hydrogen-ions concentration on the formation of intermediates (unsaturated carbonyl-containing compounds with Lambdamax225 nm and carbonyl-containing compounds with Lambdamax285 nm) of the ... see more

Low a,ß – unsaturated carbonyl compounds (LUCC) (2-propenal, crotonaldehyde) and other similar structures highly reactive organic chemicals is ubiquitously present in (cooked) foods and in the environment. Chemical reactions responsible for release of acr... see more

A synthetic approach to furyl- and benzofuryl-containing building blocks utilizing easily accessible substrates is reported. Cascade acid-catalyzed reactions of 2-methylfuran with a,ß-unsaturated carbonyl compounds or salicyl alcohols followed by oxidatio... see more

A suitable and effective scheme for the synthesis of 3,7-disubstituted [1,2,4]triazolo[4,3-a]pyrazin-8(7H)-ones has been suggested and tested. It can provide a wide chemical diversity of the final products containing practically any substituent in positio... see more

In this work, the kinetics of Meerwein–Ponndorf–Verley chemoselective reduction of carbonyl compounds was studied in monolithic continuous-flow microreactors. To the best of our knowledge, this is the first report on the MPV reaction kinetics ... see more

During the prevention and treatment of cardiovascular diseases, first cause of deaths in the world, diet has a vital role. While nutrition programs for the cardiovascular health generally focus on lipids and carbohydrates, effects of proteins are not well... see more

a,ß-Unsaturated compounds containing aldehyde, ketone, nitrile and ester functional groups are versatile precursor for the synthesis of novel organic molecules. All these compounds undergo Michael addition of carbon and other nucleophiles at b-carbon atom... see more
