A mild, efficient and versatile method has been developed for the two step synthesis of phenanthridine ring systems using the Suzuki and the modified PictetâSpengler strategy. The strategy involves synthesis of a substrate in which an aryl amine is tethered to an activated arene ring at the carbon ortho to the activated carbon nucleophile so as to facilitate the formation of phenanthridine ring viaÏ-cyclization.
开发了一种温和、高效且多用途的两步合成
菲啶环体系的方法,采用了铃木反应和改良的皮克特-斯彭格勒策略。该策略涉及合成一种底物,其中芳胺通过与活化碳亲核试剂邻位的碳原子连接到活化芳环上,以便通过π环化促进
菲啶环的形成。
