SYNTHESIS OF A NEW TRIETHYLENETETRAMINE HOMOLOG CONTAINING 4 OPTICALLY PURE CENTERS . SOME STEREOSELECTIVE COBALT(3) ION COMPLEXES OF THIS LIGAND

The synthesis of a new tetramine ligand, a homolog of triethylenetetramine which contains four optical centers, is reported. It is N,N′-bis(L-2-amino-3-phenylpropyl)-trans-D-1,2-cyclohexanediamine. The syntheses of the L-cis-β- and optically active trans-cobalt(III) perchlorate derivatives are reported. Absorption and optical rotatory dispersion spectra are reported and used, along with some chemical data, to assign the configurations of the isomer. © 1969, American Chemical Society.
