title: One-pot synthesis of D-glucosamine and chitobiosyl building blocks catalyzed by triflic acid on molecular sieves.
abstract: Combining triflic acid-catalyzed acetalation, benzylation, reductive ring opening of benzylidene acetal and glycosylation in one-pot transformations leads to a wide range of d-glucosamine building blocks for assembling oligomers.
