The synthesis of a homologous series of compounds related to the anti-HIV active class of compounds known as (S,S)-isodideoxynucleosides has been completed by a convergent route using a modified carbohydrate intermediate. This precursor, synthesized from D-glucose, was coupled with a variety of natural purine and pyrimidine bases to regiospecifically afford the desired new class of compounds.

Starting from D-glucose the syntheses of the title compounds (15 and 25) are described.Key compounds are the tetradeoxytrimethylenedithioacetals 11 and 23 which lead by the Corey-Seebach reaction with the THP-blocked 3-bromo-1-propanol to the fully blocked, open-chained products 13 and to the (S)-analogous compound.Mild cleavage of the dithiane group and the THP-protective groups yields after spontaneous cyclisation 15 and 25.The open-chained mono-ol 11 with D-configurated hydroxyl group can be converted into the L-configurated product 22 by esterification with benzoic acid/ triphenylphosphane/ diethyl azodicarboxylate.
