摘要:
A process for preparing 2',3'-dideoxyinosine comprising reducing a nucleoside of the formula IIIa or IIIb ##STR1## wherein R.sup.2 is hydrogen, C.sub.1-12 acyl, C.sub.1-12 alkyl, C.sub.7-8 aralkyl or a silyl protecting group; X is Cl, Br, or I; R.sub.5 is C.sub.1-12 acyl; H.sub.x is hypoxanthine; with hydrogen in the presence of a palladium catalyst; wherein said reduction is conducted in a solvent containing a base of pH 9-11 and wherein the solvent is acetonitrile, aqueous acetonitrile, aqueous ethyl acetate, or aqueous methanol.
