Stereochemistry of N,N′-Bis-[3-(o-ethoxyphenoxy)-2-hydroxy-propyl]-ethylendiamineN,N′-Bis-[3-(o-ethoxyphenoxy)-2-hydroxy-propyl]-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.
