摘要:The present invention relates to a process for the regioselective synthesis of compounds of the formula I, n nwherein 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 palladium catalyzed, regioselective process to a wide variety of unsymmetrical, multifunctional N-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N-substituted amides useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.

摘要:Disclosed herein are heterocyclic arynes and methods for preparing the same. Heteroarynes such as 5-membered O- or N-heterocyclic arynes have been considered inaccessible due to ring strain associated with the triple bond. The methods described herein demonstrate that these arynes can be successfully prepared through the utility of pi-backbonding from a transition metal. Synthetic utility of this method has been demonstrated by the facile synthesis and functionalization of heterocycles using these heteroaryne building blocks.
