Résumé
Abstract
The Pd-catalyzed carbon-carbon bond forming reaction between
ethynyl C-glycosides and polyiodinated benzenes (Sonogashira-Heck-Cassar
coupling) allows the introduction of various ethynylene glycoside
chains on the phenyl ring thus creating glycoside clusters wherein
the sugar moieties are linked to the benzene ring by an all carbon
tether.
