    Several 5-fluorouracil derivatives in which the phthalidyl (1, 3-dihydro-3-oxoisobenzofuran-1-yl) group, appropriately substituted on its benzene ring, is substituted at the N (1)-or N (3)-position or at both positions were synthesized, and their antitumor activities were evaluated. Among these compounds, 1-(1, 3-dihydro-3-oxoisobenzofuran-1-yl)-5-fluorouracil (3a, 590-S) was shown to be markedly active against several experimental tumor systems. Several methods for a simple and efficient large-scale preparation of 3a were examined. The large-scale preparation of 3a was effected most efficiently by the condensation of 5-fluorouracil with the quaternary ammonium salt of 3-bromophthalide in the presence of a base. The synthesis of (+)- and (-)-3a is also described.

    Nucleoside analogues of uridine, 5-bromo-, 5-iodo-, and 5-fluorouridines, thymidine and cytidine were prepared by condensing appropriately substituted 2,4-dimethoxypyrimidines with an acyclic side chain in the form of a benzoylated halo-ether, and subsequent removal of the protecting benzoyl group in base. The 2′-O-p-tosylates of these nucleoside analogues could then be modified to 2′-halo-, azido-

    Six types of 5-fluorouracil (5-FU) derivatives were synthesized ; namely, 2, 4-di-O-substituted, 2-O-substituted, 4-O-substituted, 1, 3-disubstituted, 1-substituted and 3-substituted compounds. After oral administration of these compounds to rats, the blood levels of 5-FU were determined. Among O-substituted derivatives, a 4-O-substituted derivative was most easily activated to 5-FU and 2-O-substituted derivatives were next most easily activated. Among N-substituted derivatives, acyl and sulfonyl derivatives showed the highest 5-FU releasing abilities and 1-alkoxymethyl substituted derivatives showed low ability. N-Alkyl substituted derivatives were not activated to 5-FU. Several compounds which gave higher blood levels of 5-FU than that obtained with 1-(tetrahydro-2-furyl)-5-fluorouracil (Thf-FU), as well as same related compounds, were selected and their antitumor activities were examined. The 2-O-substituted derivatives, 2-butoxy-5-fluoro-4 (1H)-pyrimidone (11) and 2-benzyloxy-5-fluoro-4 (1H)-pyrimidone (19), were as effective as Thf-FU. The activities of 2, 4-di-O-substituted derivatives, 2, 4-dibutoxy-5-fluoropyrimidine (1) and 2, 4-dibenzyloxy-5-fluoropyrimidine (6), against Ehrlich carcinoma and against sarcoma 180, respectively, were the same as those of Thf-FU. The 1-substituted derivatives, 1-ethoxymethyl-5-fluorouracil (49) and 1-(1-ethoxy-1-phenylmethyl)-5-fluorouracil (50), were found to be as effective as Thf-FU.
