The photochemically initiated dehydro-Diels-Alder (PDDA) reaction is an efficient and versatile method for the prepa- ration of biaryls. The ring closure may take place both inter- and in- tramolecularly, of which the intramolecular variant is more productive from the preparative point of view. A variety of linkers can be employed to connect the ynone moiety, which acts as the chromophore, with another
光化学引发的脱氢-狄尔斯-阿尔德 (PDDA) 反应是制备联芳基化合物的一种有效且通用的方法。闭环可以发生在分子间和分子内,从制备的角度来看,分子内变体的生产效率更高。可以使用多种接头将充当发色团的ynone部分与另一个乙炔基团连接起来,从而实现大的结构多功能性。此处还将讨论影响 PDDA 反应位点选择性的原理。
