When nitric oxide was bubbled into acetonitrile under aerobic conditions, the solution showed a cobalt-blue color. Addition of guanosine into the solution generated N2-acetylguanosine as a major product. The result of the reaction using 15N labeled acetonitrile indicated that the nitrogen atom of the acetylated exocyclic amino group on N2-acetylguanosine originated from acetonitrile. We discuss the reaction mechanism for the acylation.
