Synthesis of indoles and quinazolines <i>via</i> additive-controlled selective C–H activation/annulation of <i>N</i>-arylamidines and sulfoxonium ylides
Selective synthesis of indoles and quinazolines was achieved through a precise control of C–H activation/annulation by changing additives.
通过改变添加剂,通过精确控制C-H活化/环化实现了对吲哚和喹唑啉的选择性合成。

An efficient and selective Pd(0)-catalyzed sp3 CâH bond arylationâoxidation of 4-methylquinazolines is reported. The method enables the introduction of arylketone at the benzylic position of 4-methylquinazolines without the use of an additional directing group, and atmospheric oxygen is used as the sole oxidant.
