    摘要: Some new 1-(2- or 3-deoxy-.beta.-D-pentofuranosyl)-2-thiouracils and 1-.beta.-D-pentofuranosyl-2-thio-6-azauracils have been prepared. Further, it has been found that the known nucleoside compound, 1-.beta.-D-ribofuranosyl-2-thiouracil is active against Herpes virus and against L-1210 leukemia in mice. An improved method of preparing corresponding 2-0-methyluracil and 2-0-methyl-6-azauracil intermediates is described. The method preserves the .beta.-configuration of the starting nucleoside.
