A series of 6-deoxymollugins were prepared five steps from benzaldehyde and its derivatives via phenylboronic acid-catalyzed chromenylation as a key step. Their inhibitory activities against tyrosinase from mushroom were evaluated to show that the parent, methyl 2,2-dimethyl-2H-benzo[h]chromene-5-carboxylate (9a) showed best and promising inhibitory activity at IC50 = 18.3 μM.
