Cu(ii)-catalyzed annulation of α,β-unsaturated ketoxime acetates with 3-formylchromones for the synthesis of functionalized 2,4-diarylpyridines

Abstract

A novel synthesis method has been developed for the construction of functionalized 2,4-diarylpyridines. The reaction involves several key processes, including a reduction reaction, Michael reaction, decarboxylation, intramolecular cyclization, oxidation, ring-opening...
