A dramatic concentration effect on the stereoselectivity of N-glycosylation, which is attributable to a low-concentration-facilitated remote-participation, has been disclosed, leading to convenient synthesis of the 2â²-deoxy-β-ribonucleosides of biological significance.

Simple building blocks were used for the total synthesis of miharamycin B and its biosynthetic precursor. The key step in the strategy was the de novo construction of the pyranose moiety through Achmatowicz rearrangement. The purine ring was introduced by palladium-catalyzed N-glycosylation.
