New Stereospecific Method of Synthesis of [Sp]- and [Rp]-Dinucleoside-(3',5') Methanephosphonates
摘要:
Using a stereoretentive reaction between diastereomerically pure 5'-O-DMT-(N-protected) nucleoside 3'-O-(Se-methyl methanephosphonoselenolate)s and 3'-O-acetyl-(N-protected) nucleosides, diastereomerically pure dinucleoside-(3',5') methanephosphonates as well as ''all-Rp'' and ''all-Sp'' trimers, tetramers, and pentamers were synthesized.
