6-(Acylmethyl)-7-hydroxypteridines 7-14 as well as the isomeric 7-(acylmethyl)-6-hydroxypteridines 15-22 were prepared by condensation of 5,6-diaminouracils 1 and 2 with ethyl aroylpyruvates 3-6 in pyridine and hydrochloric acid, respectively. The structures of the newly synthesized compounds were confirmed by their hydrolysis into the 7-hydroxy-6-methyl-23, 24 and 6-hydroxy-7-methylpteridines 25 and
通过将5,6-二氨基尿嘧啶1和2与芳酰基丙酮酸乙酯3-6在吡啶中缩合制备6-(酰基甲基)-7-羟基吡啶7-14以及异构体7-(酰基甲基)-6-羟基吡啶15-22。和盐酸。新合成的化合物的结构通过它们的水解确认到7-羟基-6-甲基- 23,24和6-羟基-7- methylpteridines 25和26。还描述了2-(甲硫基)衍生物28的合成。
