N6, N6-Dimethyl-8-methylsulfonyladenosine, obtained from N6, N6-dimethyl-8-methylthioadenosine by highly selective oxidation with KMnO4, was treated with cyanide ion to give 8-cyano-N6, N6-dimethyladenosine. The conversion of the cyano group to methyl imidate, methoxycarbonyl, carbamoyl, carbothioamide, and carboxylic acid moieties was achieved. These 8-substituted N6, N6-dimethyladenosines may possess resonances structures involving positions 6 and 8 in adenosine, as indicated by the spectroscopic data. They showed no antitumor activity.
