tricyclic framework has been established. The multicomponent reaction utilizes a tandem, double Diels-Alder cycloaddition followed by a Nazarov reaction to furnish the [6-5-6] backbone. This method produces three fused rings evolving from the construction of five new carbon-carbon bonds, a quaternary carbon, and stereogenic centers in a one-pot reaction. The products are produced with excellent regio- and

生物相关化合物,已经建立了一种高度简洁的一锅法。多组分反应利用串联的双Diels-Alder环加成反应,然后进行纳扎罗夫反应,以提供[6-5-6]主链。此方法通过一锅反应从五个新的碳-碳键,一个季碳和一个立体中心生成的结构中产生了三个稠合环。生产的产品具有出色的区域控制和非对映控制。
