title: Convergent synthesis of oligosaccharides on the gram-scale using cetyl thioglycoside based on a hydrophobically assisted switching phase method.
abstract: A hydrophobically assisted switching phase (HASP) method is an efficient strategy for the synthesis of carrier-loaded oligosaccharides. We improved this method by using cetyl thioglycoside as the carrier, which made it possible to use the synthetic oligosaccharide block directly as the donor. We applied this improved HASP method in the successful assembly of a gp120-associated nona-mannoside. Our results indicated that the HASP method is an efficient strategy for the synthesis of complex oligosaccharides and glycoconjugates.
