An efficient procedure is established to synthesize 3',5'-dithio-2'-deoxyadenosine starting from 2'-deoxyadenosine in five steps in 33% overall yield. In this procedure, the key intermediate 9 was synthesized by twice S N 2 reactions with twice 3'-configuration inversions and then it was deprotected to title compound by removing three acyl groups in one pot.
建立了一个有效的程序来合成 3',5'-二硫-2'-脱氧腺苷,从 2'-脱氧腺苷开始,分五步,总产率为 33%。在该程序中,关键中间体9通过两次3'-构型反转的两次SN 2 反应合成,然后通过在一锅中去除三个酰基将其脱保护为标题化合物。
