Efficient Synthesis of 2',3'-Dideoxynucleosides and 2',3'-Dideoxy C-Nucleosides from D-Glucosamine

Jung, Michael E.,Trifunovich, Ivan D.

, p. 2921 - 2924 (2007/10/02)

D-Glucosamine 1 can be easily converted into 2,5-anhydro-6-O-benzoyl-3,4-dideoxygluconic acid 6 which can be taken on to both 2',3'-dideoxynucleosides such as dideoxyuridine (ddU) 4 and 2',3'-dideoxy C-nucleosides such as dideoxyformycin B 5 and dideoxyshowdomycin 20.
