New approach to the synthesis of .beta.-2'-deoxyribonucleosides: intramolecular Vorbrueggen coupling
摘要:
Silylation of the O2,5'-linked nucleoside 7 followed by treatment with trimethylsilyl triflate affords the O2,5-anhydro nucleoside 9 and its hydrolysis product the beta-anomer of the 2-deoxyuridine 10 in good yield in the first example of an oxygen-bridged intramolecular Vorbruggen coupling.
