Iminodiacetic acid containing asymmetric carbon with S chirality (H2ida(Cs); HOOCCH2NHC*HDCOOH) was prepared by stereospecific deuteration of (−)563CD-mer(O)cis(Nc)-[Co(ida)(edma)]. Using this H2ida(Cs), u-fac-[Co(ida(Cs))(mdien)]+ was prepared and optically resolved. On the basis of the 1H NMR spectra of the chelating ida(Cs), the absolute configuration of the (−)550CD isomer was assigned to ΔΛΔ.
