Novel 1'-homo-N-2'-deoxy-α-nucleosides: synthesis, characterization and biological activity.

ABSTRACT: For the first time, a series of novel 1'-homo-N-2'-deoxy-α-nucleosides containing natural nucleobases as well as 5-fluoro and 5-iodopyrimidine analogs have been synthesized in an efficient manner. Additionally, a high yield protocol for the assembly of a dimeric scaffold containing two sugar moieties linked to the N-1 and N-3 positions of a single pyrimidine base has been accomplished. The structures of the novel homonucleosides were established by a single crystal X-ray structure of 1'-homo-N-2'-deoxy-α-adenosine and NMR studies. The biological activity of these 1'-homo-N-2'-deoxy-α-nucleosides as antiviral (HIV-1 and HBV) and cytotoxic studies was measured in multiple cell systems. The unique structure and easy accessibility of these compounds may allow
