The synthesis of nucleosides 15–19 has been completed in high yield following the method of Hilbert–Johnson, by condensation of 2,4-dimethoxypyrimidine with bromo-4-deoxypento pyranosides in which the C-3 hydroxyl group is free. The presence of this group augments the reactivity of the bromides but does not appear to play an important role in the stereochemistry of the reaction, which is above all influenced by steric factors and the nature of the C-2 substituent.
