Abstract
The syntheses of N,N′-dibenzyl-2,4-diaminopyrimidine-2′-deoxyribonucleoside and 1-methyl-2′-deoxypseudoisocytidine via Heck coupling are described. A survey of the attempts to use the Heck coupling to synthesize N,N′-dibenzyl-2,4-diaminopyrimidine-2′-deoxyribonucleoside is provided, indicating a remarkable diversity in outcome depending on the specific heterocyclic partner used.
