Cycloaddition of diazomethane with 3′-deoxy-3′-methylene- and 4′,5′-didehydro-5′-deoxynucleoside derivatives followed by sensitized photochemical extrusion of nitrogen provided the previously unreported 3′- and 4′-spirocyclopropane nucleoside derivatives. Enhancement of the cycloaddition reactions by electron withdrawing benzoyl protecting groups was observed.
