Abstract
Fifteen glycosides of 1-arylsulfonyl-5-fluorouracil were synthesized by the reaction of 1-arylsulfonyl-5-fluorouracil with bromoacetylglucose or bromoacetylxylose under phase transfer catalysis. Their structures were confirmed by IR, 1HNMR, and elementary analysis. Preliminary results of in vitro tests showed that some of them have certain antitumor activities.
