2′-Deoxy-3′-thio-5′-O-(4-monomethoxytrityl)-6-N-benzoyladenosine (1a) has been prepared from adenosine in seven steps and, following conversion of to a 3′-S-phosphorothioamidite, used to synthesize a dinucleoside 3′-S-phosphorothiolate containing 2′-deoxy-3′-thioadenosine. The procedure is compatible with automated methods of DNA synthesis and extends the potential of the recently developed phosphorothiolate
由腺苷分七步制备2'-脱氧-3'-硫代-5'-O-(4-单甲氧基三苯甲基)-6-N-苯甲酰腺苷(1a),然后将其转化为3'-S-磷硫代酰胺,用于合成含有2'-脱氧-3'-硫代腺苷的二核苷3'-S-硫代磷酸酯。该程序与DNA合成的自动化方法兼容,并扩展了最近开发的硫代磷酸酯方法对DNA进行链特异性切割的潜力。
