A general route to D- and L-six-membered nucleoside analogues.
A simple synthetic route for novel L-(as well as D-) six-membered nucleosides is described. Particularly, we have provided a general approach to the synthesis of azasugar-based nucleosides, which preparation has been easily achieved starting from the coupling of our three carbon homologating agent 1 with the well known Garner aldehyde 4. Further suitable and stereocontrolled functionalizations of the intermediate 9 will provide, after the base insertion, a wide class of six membered modified azanucleosides to be tested as NRTIs.
