We will discussed mainly the synthesis of famciclovir which is one of the purines' nucleoside compounds. The famciclovir was synthesized from purine by a series of steps by Acylation, Decarboxylation, Reduction ,and so on; Derivatives of these intermediates is described from the 6-chloro- 9H- purin-2-amine as raw materials in different conditions when the iodine and bromide were synthesized with the addition of two intermediate 6-bromo-9H-purin-2-amine and 6-iodo-9H-purin-2-amine; There is elaborated from the main part of a acetophenone, urineaminohydrochloride, phenylhydrazine, ethyl acetoacetate as raw material through a series of reactions to synthetic 3-phenyl-4-formylphenyl pyrazole and 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-aldehyde two pyrazole aldehyde, and then with 2-amino-6-chlorine-9-(2-methicillin-oxo-co-methyl-4-yl) purine reaction of the two new pyrazole purine Schiff bases.
本论文主是采用以鸟嘌呤为原料，经过一系列的酰基化，脱羧，还原等反应作用下最终得到了产物2-氨基-9-(4-乙酰氧基-3-乙酰氧基甲基丁基)嘌呤(法昔洛韦)；其中的中间体衍生物主要是阐述从以2-氨基-6-氯鸟嘌呤为原料通过在不同的条件下进行溴代与碘代分别合成了另外两种中间体2-氨基-6-溴鸟嘌呤及2-氨基-6-碘鸟嘌呤；还有一部分主要是阐述从以苯乙酮，盐酸氨基脲，苯肼，乙酰乙酸乙酯为原料通过一系列的反应先合成3-苯基-4-醛基吡唑及5-氯-3-甲基-1-苯基-1H-吡唑-4-甲醛这两个吡唑醛，然后再与2-氨基-6-氯-9-(2-甲氧羰基丁酸甲酯-4-基)嘌呤反应得到了两个新型的吡唑嘌呤席夫碱。
