Abstract

A dinucleoside monophosphate, 8,2'-anhydro-8-mercapto-9-beta-D-arabinofuranosyladenine phosphoryl-(3'-5')-inosine (AspI) was synthesized by the condensation of protected 8-mercapto-adenosine 2',3'-cyclic phosphate and 2',3'-isopropylideneinosine with diphenylphosphorochloridate. 8-Mercaptoadenosine 2',3'-cyclic phosphate was polymerized by using tetraphenyl pyrophosphate as the condensing reagent. As oligonucleotides, thus obtained, contained some uncyclized 8-mercaptoadenosine residues and were cleaved at these sites with 0.3N KOH. As 5'-phosphate was synthesized and polymerized with DCC to give oligonucleotides with chain lengths 2 to 9.

摘要

一种二核苷单磷酸,8,2'-脱水-8-巯基-9-β-D-阿拉伯呋喃糖基腺嘌呤磷酸-(3'-5')-肌苷(AspI),是通过将受保护的8-巯基腺苷2',3'-环磷酸酯和2',3'-异丙叉肌苷与二苯基磷酰氯缩合而成。8-巯基腺苷2',3'-环磷酸酯以四苯基焦磷酸酯作为缩合试剂进行聚合。如此获得的寡核苷酸含有一些未环化的8-巯基腺苷残基,并在这些位点被0.3N氢氧化钾裂解。合成5'-磷酸并与二环己基碳二亚胺聚合,得到链长为2至9的寡核苷酸。
