The intermolecular pinacol-like coupling of optically active imines was performed stereoselectively with metallic samarium and a catalytic amount of iodine to give chiral C2-2,2'-ethylenediimino-diethanol derivatives.

Novel (S)-valinol-based chiral C2-2,2'-ethylenediiminodiethanol derivatives 4a and 4b have been synthesized and used as chiral catalysts in the enantioselective addition of diethylzinc to aldehydes. (R)-1- Phenylpropanol has been obtained in up
