Abstract
The asymmetric coupling reaction of 2-hydroxybenzo[c]phenanthrenes by using Cu–chiral diamine under atmospheric air is described. The use of CuCl-(–)-sparteine and CuCl-cyclohexanediamine derivatives was found to be highly effective to give the helical quinone derivatives in a good yield with high percent enantiomeric excess.
