Abstract

Results and Discussion As mentioned above, protection of the amino groups of adenosine and cytidine with the usual acyl groups should be avoided in our approach that involves hydrazine treatment. Therefore, we have chosen a trityl-type protecting group for the above nucleoside bases. Although both DMTr and MMTr are available for adenosine, the former required inconvenient column chromatography in the presence of pyridine because of its ...
