corresponding thioesters is described. This procedure has been used for the preparation of a ribonucleoside disulphide (8d), a key intermediate for the synthesis of oligoribonucleotides containing 3′-S-phosphorothiolate linkages. The regioselectivity of the Arbusov reaction of 8d with phosphites has been examined. The X-ray structure of 3′-deoxy-3′-S-(2-nitrophenyldisulfanyl)thymidine (9b) is also reported
描述了由相应的硫酯制备S-核苷基S-芳基二硫化物的一般方法。该方法已经用于制备核糖核苷二硫化物(8d),核糖核苷二硫化物(8d)是合成含有3'- S-硫代磷酸酯键的寡核糖核苷酸的关键中间体。研究了8d与亚磷酸酯的Arbusov反应的区域选择性。还报道了3′-脱氧-3′- S-(2-硝基苯基二硫烷基)胸苷的X射线结构(9b)。
