inhibitory effects on the diphenolase activity of mushroom tyrosinase were evaluated. The results showed that some of the synthesized compounds exhibited significant inhibitory activity, and four compounds exhibited more potent tyrosinase inhibitory activity than the reference standard inhibitor kojic acid (5‐hydroxy‐2‐(hydroxymethyl)‐4H‐pyran‐4‐one). Specifically, 1‐(‐1‐(4‐methoxyphen‐ yl)‐3‐phenyl
