Abstract

Facile, one-pot synthesis was developed for several β (1→ 2)-, β (1→ 3)-or β (1→ 4)-linked disaccharides from fully unprotected methyl hexopyranosides according to the molecular recognition by arylboronic acids. The methodology was successfully applied to facile, short step assembly of the trisaccharide fragment of type II arabinogalactan.
