Synthesis of 3'-amino and 5'-amino hydantoin 2'-deoxynucleosides

El-Barbary,Khodair,Pedersen,Nielsen

, p. 707 - 717 (2007/10/02)

3'-Amino and 5'-amino derivatives of hydantoin 2'-deoxynucleosides have been prepared from the corresponding 3'-phthalimido and 5'-azido nucleosides, respectively, which in turn were prepared by condensation of appropriate sugars with 5-benzylidenehydantoin. The amino nucleosides were tested for their potential activity against HIV and HSV.
