The ability of the guanidinylating reagent N′,N′′-diBoc-N-triflyl-guanidine (GN-Tf) to react with in situ formed free amines from azides in carbohydrate scaffolds was explored. This reaction proved to be an efficient method to prepare guanidine derivatives in a one-pot manner with good to excellent yields, either with primary or secondary azides with different substitution patterns.
