The reaction of 2-cyano-2-methyl propanal with 2'-O-aminooxymethylribonucleosides leads to stable and yet reversible 2'-O-(2-cyano-2,2-dimethylethanimine-N-oxymethyl)ribonucleosides. Following N-protection of the nucleobases, 5'-dimethoxytritylation and 3'-phosphitylation, the resulting 2'-protected ribonucleoside phosphoramidite monomers are employed in the solid-phase synthesis of three chimeric RNA sequences, each differing in their ratios of purine/pyrimidine.
