Publication Date


Abstract The complexes of formula [CuSu 2Am 2 *] formed in situ from amino steroids (Am *) and a methylene chloride solution of the complex [CuSu 2Pr 2] (Su: succinimidate; Pr: isopropyl amine) show in the range of the d-d bands two Cotton effects at approx. 700 (Band I) and 600 nm (Band II), whose signs are correlated with the preferred torsion angle of the H 2N-Cu moiety: a positive torsion angle leads to a positive CD-band I and to a negative CD-band II. These complexes form useful Cottonogenic derivatives of primary amino compounds.
