Tin tetrachloride → Xylocytidine

Participants

Reaction Steps

One equivalent of cytosine is condensed with one equivalent of 1-O-acetyl-2,3,5-tri-O-benzoyl-α-D-xylofuranose at ambient temperature, in anhydrous acetonitrile, in the presence of tin tetrachloride, SnCl4 (2 equivalents); the compound obtained is purified by chromatography on a silica column and debenzoylated using a methonal solution saturated with ammonia gas. This gives 1-(β-D-xylofuranosyl)-cytosine.
