Abstract 2,6-Disubstituted 4-pyridyl nonaflates including methyl, phenyl, 2-thienyl and 2-furyl groups were prepared by cyclocondensation reactions of the appropriate β-ketoenamides. Palladium-catalyzed cross-couplings (Suzuki–Miyaura, Mizoroki–Heck and Sonogashira reactions) led to buildings blocks that are direct precursors for the envisioned synthesis of push–pull solvatochromic dyes. 2,6-Disubstituted
摘要 通过适当的β-酮烯酰胺的环缩合反应制备包括甲基,苯基,2-噻吩基和2-呋喃基的2,6-二取代的4-吡啶基壬酸酯。钯催化的交叉偶联(Suzuki–Miyaura,Mizoroki–Heck和Sonogashira反应)导致结构单元成为设想的推挽式溶剂化染料的直接前体。 通过适当的β-酮烯酰胺的环缩合反应制备包括甲基,苯基,2-噻吩基和2-呋喃基的2,6-二取代的4-吡啶基壬酸酯。钯催化的交叉偶联(Suzuki–Miyaura,Mizoroki–Heck和Sonogashira反应)导致结构单元成为设想的推挽式溶剂化染料的直接前体。
