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.

La présente invention porte sur un procédé pour la synthèse régiosélective de composés de la formule (I), dans laquelle R0 ; R1 ; R2 ; R3 ; R4 ; R5 ; R6 ; A1 ; A2 ; A3 ; A4, Q, T et J ont les significations indiquées dans les revendications. La présente invention porte sur un procédé catalysé par un métal de transition, direct, pour obtenir une large diversité de N-aminoindoles ou N-amino-azaindoles multifonctionnels de la formule (I) à partir de 2-halo-phénylacétylènes ou de (2-sulfonato)phényl-acétylènes et d'hydrazines N, N- disubstituées, utiles pour la fabrication de produits pharmaceutiques, d'agents de diagnostic, de cristaux liquides, de polymères, d'herbicides, de fongicides, de nématicides, de parasiticides, d'insecticides, d'acaricides et d'arthropodicides.
