Synthesis of Uridine with Methylene-2-thiohydantoin as 5-Substituent

5-Formyl-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)uracil (4) was synthesized from 5-formyluracil (2) and 1,2,3,5-tetra-O-acetyl-β-D-ribofuranose (3) and condensed with 2-thiohydantoin derivatives 5 by using piperidine as the catalyst to give 5-(uridin-5-yl
