The BF3-, TsOH- or HCOOH-catalyzed dimerization of 3, 4-dioxygenated cinnamate or 1-arylpropene offers a route to arylindane lignans. The structures of the products were elucidated and a mechanism is proposed for the reactions. The structures of the dimeric products assigned as aryltetralin lignans by Botta et al.
在
BF3-、TsOH- 或 HCOOH 催化下,3,4-二氧代
肉桂酸酯或 1-芳基
丙烯发生了二聚反应,为获得芳基
茚类
木脂素提供了一条途径。阐明了产物的结构,并提出了反应的机理。Botta 等人将二聚产物的结构定为芳基四氢
木质素。
