Frutinone A, a biologically active ingredient of an antimicrobial herbal extract, demonstrates potent inhibitory activity towards the CYP1A2 enzyme. A three‐step total synthesis of frutinone A with an overall yield of 44 % is presented. The construction of the chromone‐annelated coumarin core was achieved through palladium‐catalyzed CHcarbonylation of 2‐phenolchromones. The straightforward synthetic
