Abstract
d-(-)-trans-1,2-diaminocyclohexane-N, N, N', N' -tetraacetic acid [d(-)DCTA] was prepared stereospecifically in good yield by the condensation of the resolved diamine, d-(-)-trans-1,2-diaminocyclohexane, with sodium chloroacetate at 16 degrees , followed by use of a strong cation-exchanger to obtain the free acid. Distinct differences were noted in the infrared spectra of the optically active acid and the racemate. The molecular rotation of d(-)DCTA showed strong dependence on the pH of the solution. D(-)DCTA was used as a stereospecific chelometric reagent in the spectropolarimetrically monitored determination of lead.
