The selective acylation of the hydroxy groups of the nucleosides inosine 1a and 2'-deoxyinosine lb has been achieved in the presence of Candida antarctica and Pseudomonas sp. lipases in organic solvents; starting from the 5'-acetyl derivative of 2'-deoxyinosine, compound 5a, an efficient chemoenzymatic synthesis of the antiviral drug 2',3'-dideoxyinosine 1c has been achieved.
Synthesis and 1H and 13C NMR spectral characteristics of 8-bromo-2′,3′-dideoxyguanosine and 8-bromo-2′,3′-dideoxyinosine

Reaction of 2′,3′-dideoxyguanosine 1a as 5′-O-tert-butyldimethylsilyl derivative 1b and 2′,3′-dideoxyinosine 2a with bromine in acetate buffer conducted in heterogeneous medium afforded 8-bromo-2′,3′-dideoxyguanosine 3a (44% after deprotection) and 8-bromo-2′,3′-dideoxyinosine 4a (12%) respectively. The change of conformational preferences anti → syn on 8-bromo substitution of 2′,3′-dideoxynucleosides is reflected in the 1H and 13C NMR spectra by characteristic shifts of H-2′, H-3′, C-2′ and C-3′ signals.
