The first synthesis of 2, 7-anhydro-N-acetylneuraminic acid, a sialic acid, has been completed efficiently by intramolecular glycosidation of the S-(1-phenyl-1H-tetrazol-5-yl) glycoside derivative of N-acetylneuraminic acid (5) using silver triflate - bis(acetonitrile)palladium(II) chloride as a promoter.
