Photochemical reactions of 5-fluoropyrimidine bases with alcohols

Photochemical reactions of 5-fluorocytosine with primary alcohols led to 5-alkoxycytosines and 6-alkoxycytosines as the main photoproducts. These products are formed via reactive intermediates 6-alkoxy-5-fluoro-5,6- dihydrocytosines, whereas photochemical reactions of 5-fluorouracil with alcohols led to stable 6-alkoxy-5-fluoro-5,6-dihydrouracils.

Process for preparation of 6-substituted 5-fluorouracil derivatives

The reaction of certain fluorinated pyrimidine derivatives with hydrogen donor compounds to produce 6-substituted 5-fluoropyrimidines is disclosed. The products so produced are useful in germicidal and antineoplastic applications, and can be converted into 5-fluorouracil, which has known utility in cancer chemotherapy.
