摘要:
The 3'-deoxy-3'-C-(2''-hydroxyethyl)thymidine derivatives 4 and 13 were efficiently synthesized from either thymidine via a known 3'-radical allylation, or from the branched-chain furanose 5 involving the removal of the 2'-hydroxyl after stereospecific nucleosidation. The 5'-deoxy-5'-thiothymidine 20 was prepared via a regiospecific Mitsunobu coupling, providing the third unit required for the synthesis of sulfide-linked DNA analogues.
