3-dioxane (5) provided 2-amino-6-chloro-9-[2,(2,2-dimethyl-1,3-dioxan-5-yl)ethyl]purine (6) in high yield. This aminochloropurine 6 was readily converted to the antiviral acyclonucleoside 9-[4-hydroxy-3-(hydroxymethyl)but-1-yl]guanine (1) and to its 6-chloro (10), 6-thio (11), 6-alkoxy (12-17), 6-amino (20), and 6-deoxy (21) purine analogues. The guanine derivative 1 was converted to its xanthine analogue
2-氨基-6-氯嘌呤与5-(2-溴乙基)-2,2-二甲基-1,3-二恶烷(5)烷基化可提供2-氨基-6-氯-9- [2,(2,2 -二甲基-1,3-二氧杂环己烷-5-基)乙基]嘌呤(6)的高产率。该氨基氯嘌呤6易于转化为抗病毒无环核苷9- [4-羟基-3-(羟甲基)丁-1-基]鸟嘌呤(1)及其6-氯(10),6-硫代(11),6 -烷氧基(12-17),6-氨基(20)和6-脱氧(21)嘌呤类似物。鸟嘌呤衍生物1转化为其黄嘌呤类似物9。类似地,用5进行6-氯嘌呤的烷基化提供了通往1的次黄嘌呤类似物8的途径。在这9个取代的嘌呤中,鸟嘌呤衍生物1显示出对疱疹的最高活性。细胞培养物中的1型和2型单纯性病毒,在某些测试中,它比阿昔洛韦更具活性,没有证据表明对细胞有毒性。
