Discovery of N-(Naphthalen-1-yl)-N′-alkyl Oxalamide Ligands Enables Cu-Catalyzed Aryl Amination with High Turnovers
摘要:
A Class of N-(naphthalen-1-yl)-N'-alkyl oxalamides have been proven to be powerful ligands, making a coupling reaction of (hetero)aryl iodides with primary amines proceed at 50 degrees C with only 0.01 mol % of Cu2O and ligand as well as a coupling reaction of (hetero)aryl bromides with primary amines and ammonia at 80 degrees C with only 0.1 mol % of Cu2O and ligand. A wide range of coupling partners work well under these conditions thereby providing an easy to operate method for preparing (hetero)atyl amines.

modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.

An efficient copper-catalyzed carboxylation of aryl thianthrenium salts with carbon dioxide at room temperature has been developed. In combination with C−H thianthrenation, this work provides an efficient site-selective C−H carboxylation method, which may be used in the late-stage carboxylation modification of drug molecules.
