Abstract
Bis-O-thioxocarbamate derivatives of vicinal diols are reduced with tris(trimethylsilyl)silane in the presence of azobisisobutyronitrile to afford the corresponding olefins in good yields. 2',3'-didehydro-2',3'-dideoxy analogs of adenosine, guanosine, inosine, cytidine and uridine were prepared.
