An efficient stereoselective synthetic method for each stereoisomer of enantiomerically pure 2′,3′-dideoxy-3′-fluoroapiofuranosyl nucleosides was developed. The key features of this strategy are the enantiospecific fluorination of the tert-alcohol and the orthogonal protection/deprotection of the diol.
