过渡金属催化N-氨基吲哚的合成

Transition metal catalyzed synthesis of N-aminoindoles
Abstract:
The present invention relates to a process for the regioselective synthesis of compounds of the formula I, wherein R0; R1; R2; R3; R4; R5; R6; A1; A2; A3; A4, Q, T and J have the meanings indicated in the claims. The present invention provides a direct transition metal catalyzed process to a wide variety of multifunctional N-aminoindole or N-amino-azaindoles of the formula I from 2-halo-phenylacetylenes or (2-sulfonato)phenyl-acetylenes and N,N-disubstituted hydrazines, useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.
