Nucleoside analogues having a boronic acid in place of the 3-hydroxyl group of deoxyribose have been synthesized. The synthesis of 3′-dihydroxyboryl-2′,3′-dideoxyribose was based on asymmetric homologation of boronicesters with (dihalomethyl)lithium, beginning from a (silyloxymethyl)boronicester. A change of chiral director is required before introduction of the second stereocenter, and the direct
