Regioselective metal catalyst synthesis of condensed benzimidazole and azabenzimidazole

摘要

The present invention provides a compound of formula I [Formula 1] (In the formula, R1; R2; R3; R4; J1; J2; J3; J4 and G have the meanings set forth in the appended claims) about the position selective synthesis method of the compound of. The invention is also directed to pharmaceutical, diagnostic agents, liquid crystals, polymers, herbicides, fungicides, nematicides, parasiticidal agents, insecticides, useful in the preparation of acaricides and arthropodicides, 2-halo - nitroarene and N- substituted a variety of asymmetric multi-functional N- substituted direct metal to the benzimidazole or azabenzimidazole of starting formula I from amide, for example, the position selection method by palladium or copper catalyst I will provide a.
