3'-Substituted pyrimidine nucleoside derivatives are obtained in moderate to high yields by the reaction of 1-(2',3'-anhydro-5'-deoxy -4',5'-didehydro-α-L-erythro-pentofuranosyl)uracil with nucleophiles without the formation of the corresponding 2'-adduct
3′-Selective modification of a 4′,5′-didehydro-5′- deoxy-2′,3′-epoxyuridine using nucleophiles

1-(2,3-Anhydro-5-deoxy-4,5-didehydro-α-l-erythro-pent-4-enofuranosyl) uracil 4 was obtained by the treatment of 5′-iodo-2′,3′- epoxyuridine 5 with LiHMDS in excellent yield. The pyrimidine nucleoside 4 possesses quite unique vinyl epoxide moiety within th
