摘要:
3'-Thio-3'-deoxyribonucleosides (U and C) have been synthesized via Vorbruggen-type glycosylation with 3-S-benzoyl-5-O-toluoyl-1,2-O-diacetylfuranose, which was obtained from 1,2-O-isopropylidene-5-O-toluoyl-3-O-trifluoromethanesulfonyl-alpha-D-xylofuranose. 3'-Thio-3'-deoxyuridine has been converted to its phosphoramidite.
