A stereoselective and scalable route to 1,5-anhydrohexitol nucleoside analogues belonging to L-series as building blocks for L-HNA oligonucleotide synthesis has been efficiently tuned. Key to the successful outcome of our approach is the development of a DDQ-mediated domino reaction, which leads to the formation of an unsaturated 1,6-anhydrosugar derivative. Sugar elaborations and base insertion then enable to synthesize six-membered nucleosides.

Abstract
A stereoselective and scalable route to 1,5-anhydrohexitol nucleoside analogues belonging to L-series as building blocks for L-HNA oligonucleotide synthesis has been efficiently tuned. Key to the successful outcome of our approach is the development of a DDQ-mediated domino reaction, which leads to the formation of an unsaturated 1,6-anhydrosugar derivative. Sugar elaborations and base insertion then enable to synthesize six-membered nucleosides.File in questo prodotto:
