Synthesis of Difuropyridines from Chitin‐Derived 3‐Acetamidofuran and their Application to Photocatalytic Reactions

Abstract Difuropyridines have been prepared from aldehydes and chitin‐derived 3‐acetamidofuran (3AF) under acid‐catalyzed conditions. Difuropyridines were comprehensively synthesized for the first time. The synthesized difuropyridines can be applied to prepare fluorescent probe analogs or catalyze decarboxylative reactions as photocatalysts.
