, p. 2555 - 2557 (2004)
(Matrix Presented) The formation of a guanosine derivative silylated at both the O6 and amino groups was identified by 15N NMR. This intermediate allows facile reaction with acetyl chloride or phenoxyacetyl chloride to give in high yield the co

High yield protection of purine ribonucleosides for phosphoramidite RNA synthesis
Song, Quanlai,Wang, Weimin,Fischer, Artur,Zhang, Xiaohu,Gaffney, Barbara L.,Jones, Roger A.

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.
