Preparation of the 4',4-C-diaminomethyl uridine analog starting from the commercial uridine via 4',4'-C-dihydroxymethyl uridine, 4',4'- C-bis-trifluoromethanesulfonyl oxymethyl uridine, and 4',4'-C-diazidomethyl uridine in total eight steps was achieved in 8% yield. Steric hindrance between 3'-O-TBDMS and 5'-O-triflate prevented the undesired ring closure which made the synthesis of target compound feasible. (c) 2007 Published by Elsevier Ltd.
