[reaction: see text] A one-step method was developed for elaboration of a variety of polycyclic indole skeletons via a novel palladium-catalyzed intramolecular indolization of 2-chloroanilines bearing tethered acetylenes. This novel intramolecular indolization method unveils an unusual syn amidopalladation pathway of a tethered alkyne.
[反应:见正文]开发了一种一步法,用于通过新型钯催化带有链状乙炔的2-氯苯胺分子内吲哚化来修饰各种多环吲哚骨架。这种新颖的分子内吲哚化方法揭示了一种被束缚的炔烃的不寻常的合成酰胺基palladation途径。
