A newreagent, tetrabutylammonium pyridin-2-olate, was prepared and its application to the efficient synthesis of N-aryl pyridine-2-ones was demonstrated using CuI-catalyzed coupling reactions with aryl iodides. This coupling reaction is mild, high-yielding, and remarkably chemoselective (N- vs. O-arylation). It is also compatible with substrates containing labile functional groups.
制备了一种新试剂 吡啶-2-醇四丁基铵,并通过 CuI 催化与芳基碘化物的偶联反应证明了其在高效合成 N-芳基吡啶-2-酮中的应用。这种偶联反应温和、高产且具有显着的化学选择性(N- 与 O-芳基化)。它还与含有不稳定官能团的底物相容。
