Abstract
(1R*,2R*,3R*,6R*,7S*)-2-Amino-4-oxatricyclo[4.2.1.03,7]nonane-9-methanol (9) was prepared from (1R*,2R*,3R*,4S*)-bicyclo[2.2.1]hept-5-ene-2,3-dimethanol by treatment with benzyl azidoformate followed by hydrogenolysis. The amine 9 was transformed to thymine and purine nucleoside analogues. The prepared analogues were converted to corresponding Pro-Tides by treatment with methyl N-[chloro(phenoxy)phosphoryl]-L-alaninate in the presence of 1-methylimidazole or tert-butylmagnesium chloride.
