Abstract
Monophosphonylation of 2’-protected ribonucleosides (i.e., 2’-O-THP-uridine and 2’-O-THP-N6-levulinoyl-adenosine) with the bifunctional reagents bis[( 6-trifluoromethyl)benzotriazol-1-yl] methyl(phenyl)phosphonates or the analogous phosphonothioates, and subsequent addition of N-methylimidazole gave the chirally pure ‘,5’methyl(phenyl)phosphonate or phosphonothioate derivatives, respectively. Deblocking of the fully protected compounds yielded, as evidenced by X-ray analysis. the corresponding pure Sp-diastereoisomers.
