Circular dichroism is obtained only within absorption bands. Carbohydrates, but also alcohols, amines, ethers etc. are transparent in the UV-VIS region of commercially CD spectropolarimeters. In order to see Cotton effects of such compounds, new chro

The in situ formed complexes of cuprammonium solution (Cupra A) with optically active α-hydroxy acids and α-hydroxy esters show circular dichroism spectra suitable for determination of the absolute configuration of both groups of compounds. In the
