The cover art illustrates the phase-transfer catalysis effective for asymmetric Strecker reaction of ketoimines with potassium cyanide under solid-liquid biphasic conditions. Chiral 1,2,3-triazolium ion featuring prominent hydrogen-bond donating and anion-binding capabilities allows establishment a highly efficient enantioselective process preparation sterically congested chiral α-amino nitrile...

This review provides an update on our understanding of the chemical reactions (lipid oxidation, Strecker and Maillard reactions, thiamine degradation) and a discussion of the principal aroma compounds derived from those reaction or other sources in cooked meat, mainly focused on ruminant species. This knowledge is essential in order to understand, control, and improve the quality of food produc...

Many reports can be obtained on the mechanism for the Maillard reaction between amino acids and reducing sugars. Most of these reports have concentrated on the early stage of this reaction, including the formation of N-glucosides, Amadori rearrangement and the decomposition of Amadori compounds.i) In consequence, various intermediates have been identified, whose roles in the advanced stage of t...
