Novel isomeric dideoxynucleosides with S,S absolute stereochemistry and involving the transposition of the base moiety from the normal 1'- to the 2'-position have been regiospecifically and stereospecifically synthesized. The synthetic approaches involved either direct coupling with inversion at the 2-position of a preformed dideoxygenated sugar using the base moiety as nucleophile (for purine isodideoxynucleosides) or construction of the base moiety onto a stereochemically defined amino sugar precursor (pyrimidine isodideoxynucleosides). These compounds possess extremely high stability with respect to ''glycosidic'' bond cleavage and enzymatic deamination. Antiviral data suggest that the most active compound was levorotatory S,S-isodideoxyadenosine.

Approaches to the synthesis of (S) and (R) enantiomers of hydroxymethylated isodideoxynucleosides have been developed. Because of the symmetry introduced at the carbon that normally bears the -CH2OH group, these compounds have only one asymmetric center and each enantiomeric series may be viewed as being both D- and L-related.
