sulfonosine (3), was synthesized by four different routes. Acid catalyzed fusion of 6-chloropurine-2-sulfonyl fluoride (5) with 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose (8) gave a good yield of 6-chloro-9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)purine-2-sulfonyl fluoride (9). Ammonolysis of 9 furnished 4. Lewis acid catalyzed glycosylation of the trimethylsilyl derivative of either 6-chloropurine-2-sulfonamide
