5′-5′ tethered oligonucleotides via nucleic bases: A potential new set of compounds for alternate strand triple-helix formation
摘要:
The solid-phase synthesis of 5'-5'-linked oligonucleotides tethered via nucleic bases and with opposite polarities has been performed using a modified dinucleoside bearing a phosphoramidite group at the 3'-position of one nucleoside and a dimethoxytrityl group at the 3'-position of the second nucleoside.

with purines was found to be very effective for regioselective synthesis of pyranosyl N9 purine nucleosides. Based on the catalytic N-glycosylation approach, convenient synthesis of two 5′-deoxynucleosides drugs (capecitabine and galocitabine), four 2′-deoxynucleoside drugs (floxuridine, trifluridine, decitabine and cladribine), four 3′,5′-dideoxynucleoside analogues, and four 2′,5′-dideoxynucleoside

The solid-phase preparation of oligodeoxyribonucleotides covalently linked via nucleic bases with normal (3'-5') or inverted (5'-5') polarities is reported. The key-step of these syntheses is the preparation of the tethered dimers.
