Reaction of N 2 -acetyl-9- and/or -7-benzylated guanines 8 and 12 with selected alkylating agents in l-methyl-2-pyrrolidone at 120 °C yielded the guaninium salts 9 and 13. The salts were consequently transformed by phase transfer hydrogenation into

The stereoselectivity of the 1,2-trans directed, Lewis acid-catalysed azidation of peracylated furanoses was found to depend on the reactivity of the azide donor (azide nucleophilicity) and the configuration at the anomeric centre relative to the nei
