A new class of 5, 6-disubstituted uridines, in which the C-6 position was occupied by phenylthio group or iodine, were synthesized via lithiation of the corresponding 5-substituted 2', 3'-O-isopropylidene-5'-O-methoxymethyluridines and subsequent electrophilic reactions. These newly-synthesized uridine derivatives exhibited antileukemic activities against mouse leukemia L5178Y cells in culture.
