Synthesis of N3,2',3'-O-tris-(benzyloxycarbonyl)uridine and its use in the synthesis of 5'-O-(2-deoxy--d-glucopyranosyl)uridine is described. Simultaneous removal of benzyl and benzyloxycarbonyl groups was accomplished by catalytic transfer hydrogenolysis in the presence of Pearlman's catalyst without competing side reactions.
