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. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

A chemoenzymatic approach is described towards the branched tetrasaccharide repeating unit, beta-d-Galp-(14)-beta-d-Glcp-(16)-[beta-d-Galp-(14)]-beta-d-GlcpNAc, of Streptococcus pneumoniae type 14 in a form suitable for conjugation. The linear trisaccharide acceptor, beta-d-Galp-(14)-beta-d-Glcp-(16)-beta-d-GlcpNAc-(1O)CH2CH=CH2, was synthesized by coupling of peracetylated lactosyl trichloroacetimidate to a suitably protected glucosamine building block and subsequent deprotection steps. The obtained derivative was found to be a good acceptor for bovine milk beta-1,4-galactosyltransferase, and the resulting branched tetrasaccharide beta-allyl glycoside was isolated and characterized by NMR spectroscopy and FAB mass spectrometry. Reaction of the anomeric allyl function with cysteamine under UV-irradiation gave the beta-aminoethylthio-extended glycoside suitable for further coupling of the tetrasaccharide to protein carriers.
