Tyrosol, a naturally occurring phenolic compound poorly attractive as an antioxidant because of its weak efficacy, was used as starting material to obtain novelcompounds. The synthesis is based on a trifluoroacetic acid-mediated hydroarylation of cinnamic esters with tyrosol to produce 4-aryl-3,4-dihydrocoumarins, molecules of biological interest, followed by a basic hydrolysis to give the corresponding
