Abstract

Two series of novel 3-cyano-2-(2′′,3′′,4′′-tri-O-acetyl-β-D-arabinopyranosyloxy)pyridones 5a–h and 9a,b were synthesized. Microwave irradiation has been used to obtain these products in high yield under milder conditions by the reaction of 2(1H)-pyridone or its salt with an activated arabinose. The silyl method was used to obtain the same nuclesides 5a–h and 9a,b. Triethylamine was used to remove the acetyl protecting groups from the sugar moiety and to produce the free nucleosides 6a–h and 10a,b in 85–91% yield.
