  摘要：

  Alicyclic and heteroalicyclic derivatives of 9-deazaguanine (2-amino-1,5-dihydro-4H-pyrrolo[3,2-d][pyrimidin-4-one) d] [pyrimidin-4-one) are, with one exception, potent inhibitors of purine nucleoside phosphorylase (PNP) equaling the corresponding 9-arylmethyl derivatives previously investigated. The mode of binding of these compounds to PNP was determined by X-ray crystallography.

  Derivatives of 9-deazaguanine are prepared by reacting an aldehyde or ketone with a dialkylaminomalonate to form the corresponding enamine. The enamine is then reacted with a base to form a cyclic pyrrole. The cyclic pyrrole is reacted with an urea compound or a derivative of carbamimidoic acid to provide a protected guanidino compound. The guanidino is converted to the desired 9-deazaguanine derivative by reacting with trifluoracetic acid or with an alkoxide or hydroxide followed by neutralization with an acid.

  9-脱氧鸟嘌呤的衍生物是通过将醛或酮与二烷基氨基丙二酸酯反应制备相应的烯胺。然后，将烯胺与碱反应形成环状吡咯。将环状吡咯与尿素化合物或羰基脲酸衍生物反应，以提供受保护的胍基化合物。通过与三氟乙酸或烷氧化物或氢氧化物反应，然后用酸中和将胍基化合物转化为所需的9-脱氧鸟嘌呤衍生物。

  3-dimethoxypropionitrile with aldehydes followed by hydrolysis with 6 N HCl gives the unsaturated cyano aldehydes 5. Catalytic reduction of the double bond followed by reaction with diethyl aminomalonate affords the enamines 7, which cyclize to the aminopyrroles 2 on treatment with NaOMe. While the amino group in 2 is unreactive toward many guanylating reagents, acid (AcOH)-catalyzed guanylation occurs

  碱（NaOMe）催化3,3-二甲氧基丙腈与醛的缩合反应，然后用6 N HCl水解，得到不饱和氰基醛5。双键催化还原，然后与氨基丙二酸二乙酯反应，得到烯胺7，其环化为NaOMe治疗时的氨基吡咯2。尽管2中的氨基与许多鸟嘌呤化试剂没有反应性，但很容易发生酸（AcOH）催化的鸟嘌呤化反应，生成10时会与副产的甲硫醇一起生成12。随后在用碱处理时容易除去氨基甲酸酯基团和对吡咯并[3，2-d]嘧啶环系统闭环。使用HgCl（2）代替AcOH可以使硫醇结合起来，并消除了气味问题。对于不需要硫醇气味和使用汞盐的大规模反应，优选使用甲氧基类似物11。使用该程序，苯甲醛已被转化为7-（苯基甲基）吡咯并[3,2-d]嘧啶（1a），一种有效的酶嘌呤核苷磷酸化酶抑制剂，仅需三个分离步骤，总收率为31％。
