Abstract: A novel strategy for the synthesis of imidazo-fused polycyclic compounds under mild, base-free, and silver-free conditions by a rhodium(III)-catalyzed C-H annulation of alkenyl or arylimidazoles and (hetero)cyclic 1,3-dicarbonyl compounds is reported here. Such a step-economic… read more here.

Abstract: An efficient NH4I-mediated intermolecular annulation of methyl N-heteroaromatics with amines/amino acids was developed by virtue of anodic oxidation, providing a variety of functionalized imidazo-fused N-heterocycles with good to excellent yields. The practicality of this protocol… read more here.
