The present invention relates to a process for the regioselective synthesis of compounds of the formula I,
wherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4, Q 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 2H-indazoles or 2H-azaindazoles of the formula (I) from 2-halo-phenylacetylenes or (2-sulfonato)phenylacetylenes and monosubstituted hydrazines.
本发明涉及一种合成式I化合物的区域选择性合成方法,其中R0; R1; R2; R3; R4; R5; A1; A2; A3; A4,Q和J具有所述权利要求中指定的含义。本发明提供了一种直接的过渡
金属催化方法,从2-卤代
苯乙炔或(2-
磺酸酯)
苯乙炔和单取代
肼中合成广泛的多功能
2H-吲哚或2H-杂
吲哚式(I)化合物。
