The first synthesis of allenic nucleosides derived from natural ribonucleosides is reported. 2'-Deoxy-2'-(ethenylidene)cytidine (8) and 2'-deoxy-2'-(ethenylidine)adenosine (21) were prepared by a modification of the method developed by Tsuji and co-workers for the synthesis of allenes. The biological rationale for the synthesis of these compounds is discussed.
