Synthesis of a series of novel N, N-dialkyl-TsDPEN ligands and their application to enantioselective addition of dialkylzinc to benzaldehyde

A series of mono- and dialkylated derivatives of C2-symmetric N-tosyl-1,2-diphenylethylene diamines have been prepared and used as ligands for the enantiomeric control of the addition of diethylzinc to aldehydes. Addition products of up to 79% ee were formed.
