isolated from the aerial part of Verbena littoralis H. B. K. (Verbenaceae), has successfully been synthesized by employing anodic oxidation of the phenol derivative 3, as the key step. The bromine and chlorine substituents of 3 effected regioselective introduction of a methoxy group, as well as modulating the oxidation reaction. A flow-cell type apparatus of anodic oxidation provided the desired diaryl
Verbenachalcone 1,从地上部分分离马鞭草夜蛾HBK(马鞭草科),已经成功地通过采用酚衍生物的阳极氧化合成3,作为关键步骤。的溴和氯取代基的3实现区域选择性引入甲氧基,以及调制所述氧化反应。阳极氧化的流通池型设备以良好的产率提供了所需的二芳基醚4。
