Design, synthesis, and biological evaluation of novel 2′-methyl-2′-fluoro-6-methyl-7-alkynyl-7-deazapurine nucleoside analogs as anti-Zika virus agents
designed and synthesized a series of novel 6-methyl-7-acetylenenyl-7-deazapurine nucleosideanalogs as potential inhibitors of ZIKV replication. The biological activities against ZIKV replication were evaluated and the structure-activity relationship (SAR) was also studied. Among the compounds evaluated, nucleosideanalog 38 (EC50 = 2.8 ± 0.8 μM, EC90 = 6.8 ± 2.3 μM) showed the most potent anti-ZIKV

α-chiral, being derived from amino acids. This makes α-N-chiral triazoles attractive building blocks. This report describes the first enantioselective triazole synthesis that proceeds via nickel-catalyzed alkyne–azide cycloaddition (NiAAC). This dynamic kineticresolution is enabled by a spontaneous [3,3]-sigmatropic rearrangement of the allylic azide. The 1,4,5-trisubstituted triazole products, derived
