1,3,5-Tri-O-benzoyl-2-O-methyl-α-D-ribofuranose is used as a reactant in the preparation of 2'-O-methylpyrimidine ribonucleosides via stereoselective Vorbruggen glycosidation of pyrimidines. It is also used as a reactant in solid-phase synthesis, fluorescence, and ambiguous base pairing of canonical DNA nucleobases containing benzotriazole and 1,2,3-triazolo[4,5-d]pyrimidine.
