摘要:
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.
