: Organocatalysis has been recognized as a part of chemical research for long time, and it gained significant attention in catalysis recent decades. Amine catalyst is substantial type organocatalysis, successively employed the activation carbonyl compounds. This manuscript delves into exploration proline-based organocatalyst synthesis arylidene benzofuranone intermediates, critical step that facilitates subsequent construction aurone-derived azadienes. In this work, we successfully reported intermediates through Aldol condensation with different aldehydes enabled by proline-derived organic catalysts. To achieve strategy, six examples amine organocatalysts (A1-A6) were evaluated to showcase optimal transformation. Moreover, further interesting azadiene substrates its reaction TsNH2. Notably, using A6 resulted delivery product best yield (94% isolated yield). Under optimized conditions, aromatic heterocyclic containing effectively tolerated generate corresponding which converted products high excellent yield. The claimed structures confirmed spectral analysis.
