title: One-pot synthesis of glucosamine oligosaccharides.
abstract: [reaction: see text] Tuning the reactivity of glycosyl donors derived from 2-amino-2-deoxy glucose by selective introduction of different N-protecting (NPhth and NHTroc) and anomeric leaving groups (ethylthio and phenylthio) enabled highly efficient oligosaccharide synthesis in a one-pot manner. One-pot sequential glycosylation of three and four units of 2-amino-2-deoxy glucose gave trisaccharides and tetrasaccharide in 50-81% yields.
