  Glycals were found to react with a reagent system comprising of phenyliodine bis(trifluoroacetate) (PIFA) and Me3SiN3 in the presence of TMSOTf as a catalyst to form the corresponding vicinal 1,2-diazides. On the other hand, they reacted with another reagent system phenyliodine diacetate (PIDA) and Me3SiN3, also in the presence of TMSOTf as a catalyst, to lead to the corresponding vicinal 1,2-azidoacetates

  Synthesis of l‐idopyranosyl glycosyl donors starting from α‐ and β‐thio‐d‐glucopyranosides via the corresponding 5‐enopyranosides was studied for the first time. Hydroboration of the α‐configured 5‐enopyranosides proceeded with very high l‐ido stereoselectivity. After a 4,6‐O‐acetal formation, the obtained idosyl thioglycosides proved to be useful as donors in the synthesis of heparin‐related disaccharides

  The reaction of a series of anomeric thioglycosides with various glycosyl acceptors and N-iodosuccinimide/catalytic triflic acid was investigated with respect to reactivity and anomeric selectivity. In general, β-configured donors were found to give a more β-selective reaction outcome compared to their α-configured counterparts. The relative reactivity of various thioglycosides was measured through
