, p. 815 - 819 (2019/08/01)
We developed a new reaction for the one-pot synthesis of a fused cyclic compound from triphenylguanidine, which was thought to be tandem cyclization, with a moderate yield. In this reaction, conditions such as the metal reagent, oxidant, solvent, and liga

An efficient one-pot synthesis of N-aryl-substituted heterocycles by a Cu-catalyzed two-fold C-N bond formation is reported. This strategy involves a CuI-catalyzed C-N bond-forming reaction between azoles and electron-deficient bromopyridines followed by an intramolecular sp2 C-H amination. One of the products thus formed has been successfully used as a ligand for the synthesis of a Pd complex. An efficient one-pot synthesis of N-aryl heterocycles by a Cu-catalysed double C-N bond formation is reported. This strategy involves a CuI-catalysed C-N bond-forming reaction between azoles and electron-deficient bromopyridines followed by an intramolecular sp2 C-H amination.

, p. 21904 - 21908 (2014/06/23)
A copper-catalyzed synthesis of benzimidazo[1,2-a]benzimidazoles by domino addition/double cyclization of bis-(o-haloaryl)carbodiimides with primary amines was developed. A variety of the desired polycyclic benzimidazoles were efficiently and facilely assembled. Multibonds and polycyclic moieties were directly constructed in one pot. 2-Bromo-2′-iodo-diarylcarbodiimides gave good selectivity. This journal is the Partner Organisations 2014.
Copper-catalyzed domino addition/double cyclization: An approach to polycyclic benzimidazole derivatives

, p. 1749 - 1757 (2014/03/21)
An efficient and versatile method for the assembly of novel polycyclic benzimidazole derivatives has been developed by Cu-catalyzed domino addition/double cyclization reactions. A wide variety of polycyclic benzimidazole derivatives, which might be used as synthetic medicines and functional materials, were successfully assembled from bis-(o-haloaryl) carbodiimides. Unexpected N-methylated benzo[4,5]imidazo[1,2-a]indoles can also be selectively assembled. Multibonds and polycyclic moieties were conveniently formed in one pot during these domino processes.
