Two families of compounds were synthesized from a unique epoxide which was regioselectively opened by acetylide ions (for compounds II) or azide ions (for compounds III). Sequential diastereoselective glycosylation with a ribosyl fluoride derivative, Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) with various complementary azide and alkyne partners afforded the targeted compounds after final deprotection

The self-complementary UA and AU dinucleotide analogues 41–45, 47, 48, and 51–60 were prepared by Sonogashira coupling of 6-iodouridines with C(5′)-ethynylated adenosines and of 8-iodoadenosines with C(5′)-ethynylated uridines. The dinucleotide analogues associate in CDCl3 solution. The C(6/I)-unsubstituted AU dimers 51 and 54 prefer an anti-oriented uracilyl group and form stretched linear duplexes
chemical structures are rather complex. This study investigated the simplification of these naturalproducts by structure-based drug design, synthesis, and biological evaluation. We developed a simplified rigid scaffold with an arylalkyne moiety, which shows sub-micromolar MraY inhibitory activity. The scaffold is suitable for further investigating the structure–activity relationship by virtue of our

A straightforward strategy for the synthesis of triazole-containing MraY inhibitors has been developed. It involves the sequential introduction of a terminal alkyne at the S' position of an uridine derivative and O-glycosylation with a protected aminoribose leading to an elaborated alkyne scaffold. An efficient Cu (1)-catalyzed azide-alkyne cycloaddition (CuAAC) allowed the introduction of chemical diversity toward a small library of inhibitors.
