Abstract Organolithium reagents complexed with axially chiral biphenyl-substituted N,N,N′,N′-tetramethylethylenediamines (1 and 2) add to aldehydes in good enantioface selectivity. The pattern of the stereoselection, however, disagrees with that of the helical choice observed for the asymmetric polymerization of triphenylmethyl methacrylate with the same complexes.
