highly selective C-H olefination of directing-group-free indolines (C5) and tetrahydroquinolines (C6) by Pd/S,O-ligand catalysis. In the presence of the S,O-ligand, a wide range of challenging indolines, tetrahydroquinolines, and olefins was efficiently olefinated under mild reaction conditions. The synthetic potential of this methodology was demonstrated by the efficient olefination of several indoline-based
在本文中,我们报告了通过Pd / S,O-配体催化的无方向性二氢吲哚(C5)和四氢喹啉(C6)的高选择性CH烯化反应。在S,O-配体的存在下,在温和的反应条件下,有效地将各种挑战性的二氢吲哚,四氢喹啉和烯烃进行了烯化。这种方法的合成潜力已通过几种基于二氢吲哚的天然产物的有效烯化得到证明。
