A highly stereoselective synthesis of optically active trisubstituted 1,2-ethylenediamines: The first example of Grignard addition to N-diphenylphosphinoyl ketimines derived from amino acids

The efficient synthesis of optically active trisubstituted 1,2-ethylenediamines is described. Addition of aryl and/or alkyl Grignard reagents to α-amino N- diphenylphosphinoyl ketimines derived from α-amino acids was demonstrated to afford the desired tri
