Abstract
Procedure for preparing nucleosides and analogues of nucleosides of the formula < IMAGE > where A is < IMAGE > X is O, S or CH2 R1 is H, alkyl of 1-3 carbons, -CH=CH2, -CH=CH-CH3, -CH2-CH=CH2, < IMAGE > or -C[triple bond]CH R2 is H or constitutes a carbon-carbon bond together with R3 and R3 is H, halogen, N3, CN, C=CH, OH, OCH3 or CH2OH, with R3 being able to have a cis or trans configuration, relative to the hydroxymethyl function, or with R3 constituting a carbon-carbon bond together with R2. This procedure involves condensing a glycoside included in formula I in the N-1 position of a pyrimidine derivative corresponding to an aforesaid radical A, separating the [alpha]-anomer of the compound I formed and eliminating any protecting group present. There are other methods of preparation which are described in the specification. The compounds obtained are useful for preventing and treating hepatitis B, AIDS and other infections in mammals.
