Various kinds of 5'-O-unsaturated acyl 5-fluorouridines were synthesized to obtain 5-fluorouridine derivatives with low toxicity and high antitumor activity. Antitumor activity of the compounds against L-1210 leukemia in mice was examined, and the 5'-O-4-opentenoyl derivative showed the highest antitumor activity.

With the aim of diminishing the toxicity of 5-fluorouracil (1) and obtaining biologically active derivatives of 1 suitable for oral administration, α-alkoxyalkyl groups were introduced at the 1-, 3-and 1, 3-positions of 1. Alkoxyalkylation can be effected by four methods : (i) reaction of 1-alkoxyalkyl chloride (2) with 1, (ii) reaction of acetal with 2, 4-bis (trimethylsiloxy)-5-fluoropy-rimidine, (iii) addition reaction of α-unsaturated ether with 1, (iv) aminolysis of 1-alkylthio-carbonyl-3-(1-alkoxyalkyl)-5-fluorouracil. The toxicity of the products was less than that of 1, and some of these compounds showed moderate antitumor activity against L-1210 leukemia.

The toxicity and tumor affinity of 5-fluorouracil (1) have been modified by the introduction of acyloxyalkyl group (s) at the 1-, 3- or 1, 3-position (s) of 1. 1-Acyloxyalkyl-5-fluorouracil (3), 3-acyloxyalkyl-5-fluorouracil (4) and 1, 3-bis (acyloxyalkyl)-5-fluorouracil (5) were obtained by three methods : i) the reaction of α-chloroalkyl carboxylate (2) with 1, ii) the reaction of alkylidene diacylate with 2, 4-bis (trimethylsilyloxy)-5-fluoropyrimidine, iii) partial hydrolysis of 5. Compounds 3, 4 and 5 showed antitumor activity.

With the aim of diminishing the toxicity of 5-fluorouridine (1) and obtaining biologically active derivatives of 1, various kinds of 5'-O-acyl-8-fluorouridines 2 were synthesized. The antitumor activity of the compounds against L-1210 leukemia in mice was examined. The 5'-O-heptanoyl derivative 2h showed the highest antitumor activity.
