    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, useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.

    摘要: The present invention relates to compounds of the formulae (I) and (Ib) wherein R0; R1 ;R2 ;Q; V, G and M have the meanings indicated in the claims. The compounds of the formula (I) are valuable pharmacologically active compounds. They exhibit a strong antithrombotic effect and are suitable, for example, for the therapy and prophylaxis of cardiovascular disorders like thromboembolic diseases or restenoses. They are reversible inhibitors of the blood clotting enzymes factor Xa (FXa) and/or factor VIIa (FVIIa), and can in general be applied in conditions in which an undesired activity of factor Xa and/or factor VIIa is present or for the cure or prevention of which an inhibition of factor Xa and/or factor VIIa is intended. The invention furthermore relates to processes for the preparation of compounds of the formulae (I) and (Ib), their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
