One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 7512-17-6, Name is N-Acetyl-D-glucosamine, formurla is C8H15NO6. In a document, author is Wang, Jian-Fei, introducing its new discovery. Formula: C8H15NO6.
Readily available potassium alkynyltrifluoroborates were used for organocatalytic asymmetric conjugate alkynylation of beta-enaminones. The interception of a modified binaphthol catalyst and in situ generated organodifluoroboranes proved important to access functionalized beta-alkynyl-beta-amino carbonyls and derivatives with improved chemo-reactivity and enantio-induction. Mechanistic studies revealed the impact of molecular sieves on efficiency and stereocontrol. The products undergo additional functionalization to yield a diverse set of valuable beta-alkynyl-beta-amino carbonyl scaffolds.
