9-β-D-Ribofuranosylpurine (nebularine) (9) has been synthesized by two methods. (i) 2,6-Dichloro-2',3',5'-tri-O-benzoyl-9-β-D-ribofuranosylpurine (7) on dehalogenation followed by debenzoylation using methanolic ammonia affords nebularine (9). (ii) 6-Chloro-2',3',5'-tri-O-acetyl-9-β-D-ribofuranosylpurine (18) on dehalogenation followed by deacetylation yields 9.Nebularine analogues , 9-β-D-xylofuranosylpurine (12) and 9-α-L-rhamnopyranosylpurine (15) have also been synthesized from 2,6-dichloro-2',3',5'-tri-O-acetyl-9-β-D-xylofuranosylpurine (10) and 2,6-dichloro-2',3',4'-tri-O-benzoyl-9-α-L-rhamnopyranosylpurine (13).Dehalogenation of 10 and 13 followed by deacetylation and debenzoylation with methanolic ammonia affords 12 and 15 respectively.
