N,N'-Bis--ethylene diamine (5), synthesized from racemic 1,2-anhydro-3-O-(o-ethoxyphenyl)-glycerol (1) and ethylene diamine (2) or N,N'-dibenzyl ethylene diamine (3) crystallized in two fractions with different melting points.Both of these analytically pure products gave identical two spot tl-chromatograms on achiral phases.Attempts were made to resolve the mixtures which proved to consist of configurative but not constitutive isomers.Optically pure products were synthesized from chiral precursors.
