6-Bromofuro[2,3-d]pyrimidine bicyclic nucleosides are the key intermediates for the preparation of novel furo[2,3-d]pyrimidine bicyclic nucleoside derivatives with remarkable antiviral potency. The literature protocol for their synthesis involves a multi-step procedure and palladium catalyst. In this paper, an economical and practical method was developed for their preparation via condensation of the easily obtainable 5-formyl pyrimidine nucleosides with carbon tetrabromide and subsequent cyclization promoted by copper iodide.

Key words: sulfonamide, catalyst, tetrahydrofuran, pyrrolidine
