Abstract
Fully benzylated or benzoylated phenyl selenoglycosides can be activated by the promoters iodonium di‐sym‐collidine perchlorate (IDCP) or N‐iodosuccinimide and catalytic triflic acid (NIS/TfOH cat.). The potential of the iodonium ion‐mediated glycosidations of phenyl selenoglycosides is illustrated in the chemoselective synthesis of 1,2‐cis‐or 1,2‐trans‐linked disaccharides.Keywords
