Iridium-catalyzed intramolecular C–N and C–O/S cross-coupling reactions: Preparation of benzoazole derivatives

The irdium-catalyzed intramolecular arylcarbon-hetero cross-coupling reactions with o-haloarylamides or o-haloarylamidine have been effectively achieved using KOAc and just 1 mol% catalyst. The [Ir(cod)Cl]2 was proved to be more potential for smoothly assembling functional structures benzimidazoles, benzoxazoles and benzothiazoles, which was superior to Cu- and Pd-catalyzed systems. Simultaneously, a concise and efficient synthesis of tafamidis was developed in 5-g scale.

Reactivity-controlled regioselectivity: A regiospecific synthesis of 1,2-disubstituted benzimidazoles

We demonstrate exceptional levels of regioselectivity in the tandem, animation reactions between 1,2-differentiated dihaloarenes and N-substituted amidines, The regiochemical outcome of this Cul-catalyzed reaction is achieved through a combination of N1/N2 chemoselectivity on the amidine and reactivity-controlled X1/X2 chemoselectivity on the 1,2-dihaloarene. This reaction proves to be fairly general for the regiospecific synthesis of 1,2-substituted benzimidazoles.
