A number of variously substituted phenanthridines have been synthesized using the newly developed methodology under mild conditions. The Hendrickson reagent initiated cascade annulation, which is composed of a mild conversion of stable amide precursor to highly reactive imido-carbonium intermediate and a subsequent intramolecular Friedel-Crafts reaction, successfully served as the key method.
使用新开发的方法在温和条件下合成了许多不同取代的菲啶。Hendrickson 试剂引发了级联环化,该反应由稳定的酰胺前体温和转化为高反应性的亚氨基碳中间体和随后的分子内 Friedel-Crafts 反应组成,成功地作为关键方法。
