We report high yield procedures for protection of purine ribonucleosides based on a reaction which allows concomitant highly regiospecific 2'-silylation and 3'-phosphitylation. Subsequent cleavage of the H-phosphonate monoester moiety without silyl migration provides intermediates ready for phosphitylation by standard methods to give fully protected phosphoramidites.
