ABSTRACT
A photochemical method for the synthesis of functionalized dihydrofuro[3,2-c]chromenones via intramolecular Csp3-H cross-dehydrogenative oxygenation within a warfarin framework has been unearthed. Advantages of this protocol include abundant sunlight or low-energy visible light as the energy source, mild reaction conditions, and avoidance of metal catalysts.
