simple, practical and governable palladium-catalyzed hydroformylation of terminal arylacetylenes has been disclosed. The reaction proceeds under syngas-free conditions, using readily available glyoxylicacid as the formyl source, under mild conditions, giving rise to a broad range of α,β-unsaturated aldehydes.
molecules with long fluorescence lifetimes are important for the development of lifetime‐based fluorescence imaging techniques. Herein, a molecular design is described for simultaneously attaining long fluorescence lifetime (τ) and high brightness (ΦF×ɛ) in a system that features macrocyclic dimerization of fluorescent π‐conjugated skeletons with flexible linkers. An alkylene‐linked macrocyclic dimer of bi

The invention relates to pyrazolopyrimidine derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds. The compounds of the invention are mGluR5 modulators and are therefore useful for the control and prevention of acute and/or chronic neurological disorders.
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
