3-allenic aromatic ethers with decent to excellent yields under mild reaction conditions has been described. A variety of synthetically useful functional groups are tolerated and the synthetic utility of this method has been demonstrated through a series of transformations of the allene moiety. By applying this reaction as the key step, the total syntheses of naturally occurring allenic aromatic ethers
描述了在温和的反应条件下,钯催化的苯酚和烯基碳酸酯之间的 C-O 键形成反应,以良好的收率生成 2,3-烯基芳香族醚。可以耐受多种合成上有用的官能团,并且该方法的合成效用已通过丙二烯部分的一系列转化得到证明。以该反应为关键步骤,完成了天然烯属芳香醚、桉烯和土三烯A的全合成(首次合成;4.5克规模)。
