An atom-economic approach to synthesize 1,2,4-trisubstituted pyrroles through palladium-catalyzed imine-directed intramolecular C(sp3)H amination reaction has been developed. The imine group acts as a directing group as well as an intramolecular nucleophile for the first time in intramolecular CN bonds formation reactions.
已经开发了一种通过钯催化的亚胺定向分子内C(sp 3)H氨基化反应合成1,2,4-三取代的吡咯的原子经济方法。亚胺基团在分子内C N键形成反应中首次充当导向基团以及分子内亲核试剂。
