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.
以苯甲醛及其衍生物为原料,通过苯硼酸催化的铬化反应为关键步骤,分五个步骤制备了一系列6-脱氧毛蕊花素。结果表明,母体 2,2-二甲基-2H-苯并[h]色烯-5-羧酸甲酯(9a)的抑制活性最好,IC50 = 18.3 μM。
