Several new acyclonucleoside purine and 8-azapurine analogs have been prepared from 2-amino-4,6-dichloropyrimidine (1) and 3-amino-1,2-propanediol (2a) and 4-amino-1-butanol (2b), respectively, as the starting materials. The new target compounds are: 2-amino-6-chloro-9-(2,3-dihydroxypropyl)purine (6a), 2-amino-6-chloro-9-(4-hydroxybutyl)purine (6b), 2-amino-6-chloro-9-(2,3-dihydroxypropyl)-8-azapurine
由2-氨基-4,6-二氯嘧啶(1)和3-氨基-1,2-丙二醇(2a)和4-氨基-1-丁醇(2b)制备了几种新的无环核苷嘌呤和8-氮杂嘌呤类似物,分别作为起始原料。新的目标化合物是:2-氨基-6-氯-9-(2,3-二羟丙基)嘌呤(6a),2-氨基-6-氯-9-(4-羟基丁基)嘌呤(6b),2-氨基-6-氯-9-(2,3-二羟丙基)-8-氮杂嘌呤(7a),2-氨基-6-氯-9-(4-羟基丁基)-8-氮杂嘌呤(7b),9-(2 ,3-二羟丙基)-8-氮杂鸟嘌呤(8a),9-(4-羟丁基)-8-氮杂鸟嘌呤(8b),9-(2,3-二羟丙基)-8-氮杂硫鸟嘌呤(9a)和9-(4-羟基丁基)-8-硫唑嘌呤(9b)。另外,必要的中间体嘧啶衍生物2,5-二氨基-4-(2,3-二羟丙基氨基)-6-氯嘧啶(5a)和2,5-二氨基-4-(4-羟丁基氨基)-6-氯嘧啶(5b))是新颖的。
