Abstract

Pyrimidine bases and their nucleosides were oxidatively iodinated at C-5 position by the reaction of iodine in DMF (dimethylformamide) with MCPBA (m-chloroperbenzoic acid) under mild conditions. For uracil derivatives such as uracil1a, 1,3-dimethyluracil1b, uridine1c, and 2′-deoxyuridine1d, the corresponding 5-iodo derivatives were obtained in high yields (71–95%). The iodination of cytidine3a and 2′-deoxycytidine3b was achieved in moderate yields (41–56%).
