Formation of β-Configured Thioglycosides of d -Glucosamine and d -Galactosamine and Synthesis of Protected Human Milk Oligosaccharides
The Journal of Organic Chemistry(2023)
摘要
We report on the stereoselective multigram scale preparation of cyclohexyl- and phenyl thioglycosides of 2-azido-2-deoxy-β-d-gluco- and galactopyranosides from d-N-acetylglucosamine using a catalytic and solvent-free method. Two of the prepared building blocks were used as key intermediates for the synthesis of human milk oligosaccharides LNT and LNnT in their protected form.
