Abstract
The complexes of formula [CuSu2Am2*] formed in situ from amino steroids (Am*) and a methylene chloride solution of the complex [CuSu2Pr2] (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 H2N-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.
