Popis: A general procedure for the preparation of S -nucleosidyl S -aryl disulfides from the 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.
