Jp. Scovill et al., A CONVENIENT METHOD FOR THE SYNTHESIS AND RANEY-NICKEL DESULFURIZATION OF 5'-DEOXY-5'-METHYLTHIOADENOSINE, Phosphorus, sulfur and silicon and the related elements, 85(1-4), 1993, pp. 149-152
A convenient procedure for the preparation of 5'-deoxy-5'-methylthioad
enosine is reported. Chlorination of adenosine with thionyl chloride y
ielded 5'-chloro-5'-deoxyadenosine. Reaction of 5'-chloro-5'-deoxyaden
osine with aqueous methylmercaptide anion yielded 5'-deoxy-5'-methylth
ioadenosine. Hydrogenolysis of 5'-deoxy-5'-methylthioadenosine over Ra
ney nickel in water produced 5'-deoxyadenosine. This procedure affords
a high yield of readily purified 5'-deoxyadenosine while avoiding the
use of anhydrous solvents and pyrophoric reagents. The procedure illu
strates the utility of sulfur reagents to accomplish high value added
transformations in nucleoside chemistry.
