发明名称 2'-Deoxy-5-fluorouridine derivatives, a process for producing the same and antitumor agents comprising the same.
摘要 <p>Novel 2 min -deoxy-5- fluorouridine derivatives represented by the formula; &lt;CHEM&gt; wherein R represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an acetyloxy group or a halogen atom, and n is an a integer in the range of 1 to 3 are provided. These have good antitumor activities and low toxicities and are suitable for use as antitumor agents. The new compounds may be prepared by reacting 2 min -deoxy-3 min ,5 min -di-0-acetyl-5- fluorouridine with a benzoyl halide of the formula; &lt;CHEM&gt; where hal is a halogen atom and R and n are as before, preferably in the presence of an organic base, particularly triethylamine and a solvent, particularly dioxane. </p>
