A protocol for the synthesis of C5-olefinated 2-arylchromanones in a regio- and stereoselective fashion through the ruthenium-catalyzed oxidative coupling of diversified 2-arylchromanones with various alkenes through a keto-directed, site-selective C–H activation reaction is developed. IBO = isobornyl.
