  Efficient Syntheses of 2-Chloro-2‘-deoxyadenosine (Cladribine) from 2‘-Deoxyguanosine¹

  摘要：

  We report efficient syntheses of the clinical agent cladribine (2-chloro-2'-deoxyadenosine, CldAdo), which is the drug of choice against hairy-cell leukemia and other neoplasms, from 2'-deoxyguanosine. Treatment of 3',5'-di-O-acetyl- or benzoyl-2'-deoxyguanosine (1) with 2,4,6-triisopropyl- or 4-methylbenzenesulfonyl chloride gave high yields of the 6-O-arylsulfonyl derivatives 2 or 2%. Deoxychlorination at C6 of 1 also proceeded to give the 2-amino-6-chloropurine derivative 5 in excellent yields. The nonaqueous diazotization/chloro dediazoniation (acetyl chloride/benzyltriethylammonium nitrite) of 2, 2%, and 5 gave the 2-chloropurine derivatives 3, 3'b, and 6, respectively. The selective ammonolysis at C6 (arylsulfonate with 3 or chloride with 6) and accompanying deprotection of the sugar moiety gave CldAdo (64-75% overall yield from 1).

• METHOD FOR THE PREPARATION OF 2-HALO-2'-DEOXYADENOSINE COMPOUNDS FROM 2'-DEOXYGUANOSINE

  The present invention is a method for preparing 2-halo-6-aminopurines, and more specifically for preparing the clinical agent cladribine (2-chloro-2′-deoxyadenosine, CldAdo, 4), a drug of choice against hairy-cell leukemia and other neoplasms, from 2-amino-6-oxopurines, which are readily obtained from the naturally occurring compound 2′-deoxyguanosine. According to the methods of the present invention, the 6-oxo group of a protected 2′-deoxyguanosine (1) is converted to a 6-(substituted oxy) leaving group, or alternatively to a 6-chloro leaving group, the 2-amino group is replaced with a 2-chloro group, the 6-(substituted oxy) leaving group, or alternatively the 6-chloro leaving group, is replaced with a 6-amino group or, alternatively, a 2,6-dichloro substituted compound is selectively replaced with a 6-amino group, and the protecting groups are removed.

  本发明涉及制备2-卤代-6-氨基嘌呤，更具体地说，从2-氨基-6-氧代嘌呤制备临床药物克拉德霉素（2-氯-2'-脱氧腺苷，CldAdo，4），这是针对毛细胞白血病和其他肿瘤的首选药物。2-氨基-6-氧代嘌呤可以从天然存在的2'-脱氧鸟苷中轻松获得。根据本发明的方法，保护的2'-脱氧鸟苷（1）的6-氧代基被转化为6-（取代氧）离去基，或者被转化为6-氯离去基，2-氨基被2-氯代基取代，6-（取代氧）离去基或6-氯离去基被6-氨基取代，或者选择性地用6-氨基取代2,6-二氯取代化合物，并去除保护基。
