                                    Alkyl thio-, phenyl seleno-, and phenyl thioglycosides can be prepared through short synthetic sequences based on the generation of glycosyl iodides as versatile intermediates. In addition, a novel cheap combined system (stoichiometric NBS and catalytic Bi(OTf)(3)) has been developed for rapid and efficient activation of a wide variety of thio- and selenoglycoside donors.
