A tandem catalytic process for 1,3- and 1,4-bisarylation of donor–acceptor (D–A) cyclopropanes and cyclobutanes is disclosed. This strategy capitalizes on the use of two distinct sources of nucleophilic and electrophilic arylating agents, affording the formation of two new C–C bonds in an orchestrated multicomponent fashion with the aid of a catalytic Lewis acid. Mechanistic investigations have revealed it to be a stereoselective process, and products could be easily elaborated into other useful compounds.

供体-受体环丙烷和环戊二烯与富含电子的芳烃和高价Arylbismuth试剂的多组分串联1,3-和1,4-双芳基化。

公开了一种供体-受体(DA)环丙烷和环丁烷的1,3-和1,4-双芳基化的串联催化方法。该策略利用了亲核和亲电芳基化剂两个不同来源的使用,借助路易斯酸催化,以协调的多组分方式形成了两个新的C-C键。机理研究表明,这是一个立体选择过程,可以很容易地将产品精加工成其他有用的化合物。
