    以Baylis-Hillman加成物为起始原料,经过氢溴酸溴代,得到溴代物2,再与2-萘酚反应得到醚化物3;首次报道利用Pd（OAc）2/Cu（OTf）2复合催化剂催化醚化物3的环化反应,得到4个3,4-二氢香豆素类衍生物（4a~4d）,并通过1H NMR和MS进行表征。

    Aryl allyl ethers（3） were synthesized by bromation and esterization of Baylis-Hillman adducts（1）.Four 3,4-dihydrocoumarin derivatives were obtained by cyclization of aryl allyl ethers（3） in the presence of Pd（OAc）2/Cu（OTf）2.The structures were confirmed by 1H-NMR and MS.
