Investigation of the Complexation Between Quinidine Carbamate and the Enantiomers of 3‐Chloro‐1‐phenyl‐propanol by Circular Dichroism and UV Spectroscopy

UV and circular dichroism spectroscopic measurements showed that the molecular interactions in hexane/ethyl‐acetate solutions between dihydroquinidine tert‐butylcarbamate, used as a model for the quinidine carbamate chiral selector (QD), and 3‐chloro‐1‐phenyl‐propanol are too weak to affect the corresponding spectra of these compounds. The weak interactions between QD and 3‐chloro‐1‐phenyl‐propanol are probably masked by the formation of self‐associated dimeric structures in solution.
