e (7b) compounds. Treatment with diluted acid followed by potassium cyanide treatment and acid hydrolysis afforded 6-substituted 3-(purin-9-yl)- and 3-(2-aminopurin-9-yl)-2-hydroxypropanoic acids (8-10). Reaction of compounds 3 with malonic acid in aqueous solution gave exclusively the product of isomerisation, 6-substituted 4-(purin-9-yl)-3-butenoic acids (15).
用溴乙醛二乙缩醛将6-氯嘌呤和2-氨基-6-氯嘌呤烷基化,得到6-氯-9-(2,2-二乙氧基乙基)嘌呤(3a)及其2-氨基同源物(3b)。用伯胺和仲胺处理化合物3,得到N6-取代的腺嘌呤(5a-5c)和2,6-二氨基嘌呤(5d-5f)。3的水解产生次黄嘌呤(6a)和鸟嘌呤(6b)衍生物,而它们与硫脲的反应产生6-硫烷基嘌呤(7a)和2-氨基-6-硫烷基嘌呤(7b)化合物。用稀酸处理,然后进行氰化钾处理和酸水解,得到6-取代的3-(嘌呤-9-基)-和3-(2-氨基嘌呤-9-基)-2-羟基丙酸(8-10)。化合物3与丙二酸在水溶液中的反应仅产生异构化的产物6-取代的4-(嘌呤-9-基)-3-丁烯酸(15)。
