Autor: Rsuini U. Gutiérrez, Mayra Hernández-Montes, Aarón Mendieta-Moctezuma, Francisco Delgado, Joaquín Tamariz
Publikováno v: Molecules, Vol 26, Iss 13, p 4092 (2021)
An efficient synthesis of ketimines was achieved through a regioselective Hg(I)-catalyzed hydroamination of terminal acetylenes in the presence of anilines. The Pd(II)-catalyzed cyclization of these imines into the 2-substituted indoles was satisfact
