A new approach was developed for the synthesis of 5'-(Z)-substituted 4',5'-unsaturated adenosines, potential inhibitors against S-adenosyl-L-homocysteine hydrolase (SAHase). A highly stereoselective radical-mediated sulfur-extrusive stannylation was employed as a key step in the present approach. Inhibitory activity of the compounds against SAHase is also presented.
