properties of ribofuranosyl N-phenyltrifluoroacetimidates toward carboxamide sidechains of asparagine and glutamine were investigated. Conditions were found that promote nearly exclusive formation of the α-anomerically configured N-glycosides. The strategy allows for the synthesis of Fmoc-amino acids suitably modified for the preparation of ADP-ribosylated peptides. Furthermore, ribosylation of serine with
