Highly Enantioselective Imino Pinacol Coupling Leading to the Synthesis of 1,2-Diphenylethylenediamine Derivatives

Abstract
Enantioselective imino pinacol coupling of p-anisylbenzalimine was promoted by the use of Zn-Cu couple in the presence of (+)-camphorsulfonic acid to give (R,R)-1,2-diphenylethylenediamine derivative in high enantiomeric purity.
