초록

Pyrimidine bases and their mucleosides 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 uracil 1a. 1, 3-dimethyluracil 1b, uridine 1c, and 2'-deoxyuridine 1d, the corresponding 5-iodo derivatives were obtained in high yields (71-95%). The iodination of cytidine 3a and 2'-deoxycytidine 3b was achieved in moderate yields (41-56%).
