New catalists and procedures for the dimethoxytritylation and selective silylation of ribonucleosides

Article abstract of DOI:10.1139/v82-165

Procedures have been developed for the selective formation of (a) 2',5'-silylated ribonucleosides and (b) 3',5'-silylated ribonucleosides.These procedures also permit the selective silylation at either the 2'- or 3'-position of dimethoxytritylated ribonuc
