An effective process was developed for the preparation of tamibarotene via an Ullmann-type coupling in a nonpressurized l-proline/DMSO system. Notable features were the telescoping of reactions, avoiding environmentally hazardous materials, and an accepta

Herein, we report the natural ligand quebrachitol (QCT) as a promoter for a Cu(II) catalyst, which is highly effective for N-Arylation of various amines and related aryl halides. A series of diarylamine derivatives were obtained in high yields by using diethylene glycol (DEG) as both ligand and solvent. The C-N coupling reactions proceed under mild conditions and exhibit good functional group tolerance.
