Stereoselective synthesis of the complete family of optically active dideoxygenated nucleosides of the apiose family have been developed. The chiral aldodiol system 7, a key intermediate in this synthesis, was prepared from the prochiral molecule 6, through the action of the lipase from Candida cylindracia. Approaches to novel enantiomeric and diastereoisomeric dideoxynucleosides containing the te

[reaction: see text] A new solublepolymersupportsynthesis of nucleosides is described. The photochemical ring expansion of cyclobutanones in the presence of poly(ethylene glycol) (PEG) results in polymer-supported ribosides. These photoadducts can be cleaved from the polymer under Vorbruggen coupling conditions with TMS-protected purines and pyrimidines to give ribonucleosides. The method has been

Novel 2′,3′-dideoxynucleosides, having the pentofuranosyl oxygen at the 2′-position, were obtained by a short synthetic route from diethyl malonate and bromoacetaldehyde dimethyl acetal. The results of biological testing against HIV-1 in vitro are presented.
