Two L-ribosyl donors were synthesised from L-xylose, then submitted to a glycosidation reaction according to Vorbruggen's conditions to furnish L-ribonucleosides in high yield.
Synthesis of 3′-azido- and 3′-amino-3′-deoxyadenosine in both enantiomeric forms
derivative of 3′-amino-3′-deoxyadenosine, is one of the most important examples. Some azidosugar nucleosides, the synthetic precursors of the corresponding aminosugar compounds, are known to be active againstHIV reverse transcriptase. We are interested in comparing the bioactivity of D- and L-enantiomers of such nucleosides. Here, the synthesis of both D- and L-enantiomers of 3′-azido- and 3′-amino-3′-deoxyadeonsine
