A synthesis has been developed providing nucleotide dimers comprising natural or unnatural nucleoside residues. A ribonucleoside 5-phosphorimidazolide is added to a nucleoside adsorbed on montmorillonite at neutral pH with the absence of protecting groups. Approximately 30% of the imidazolide is converted into each 2-5 dimer and 3-5 dimer with the rest hydrolyzed to the 5-monophosphate. Experiments with many combinations have suggested the limits to which this method may be applied, including heterochiral and chimeric syntheses. This greener chemistry has enabled the synthesis of dimers from activated nucleotides themselves, activated nucleotides with nucleosides, and activated nucleotides with nucleotide 5-monophosphates.

A study of four different O-4 and N-3 protected uridine derivatives, 4 to 7, for their stabilities under different conditions versus their abilities to undergo nucleophilic substitution reaction at C-4 by an appropriate oxygen or a nitrogen nucleophile has established a general strategy for the site-specific modification of a particular pyrimidine residue in a model fully protected diuridylic acid to give either UpC, CpC or UpU, depending upon the deprotection condition.
