Copper and zinc co-catalyzed synthesis of imidazoles via the activation of sp3 C–H and N–H bonds
摘要:
An efficient and facile approach to synthesize imidazoles from amidines and arylketone via oxidative coupling of sp(3) C-H bond and N-H bond is reported. This strategy exhibits high performance in terms of regioselectivity with moderate to high yields by using easily available materials, and provides an alternative method to synthesize multi-substituted imidazole skeletons.

Methyltriphenylphosphoniumtribromide acts as an efficient mild dethioketalization reagent with high selectivity for 2-phenyl and 2-vinyl 1,3-dithiannes versus 2-alkyl 1,3-dithiannes and without any secondary brominationreaction of the investigated substrates. The reaction was also successful with trimethylphenylammonium tribromide.
