Abstract: An efficient method for the synthesis of flavones and γ‐benzopyranones has been developed utilizing a mild Sonogashira coupling and 18‐crown‐6 ether mediated 6‐endo cyclization of o‐alkynoylphenyl acetates. By using this strategy, flavones and γ‐benzopyranones bearing electron‐donating groups, halogens, and simple alkyl substituents were synthesized in satisfactory yields.
