Circular dichroism of 5-alkyl-5-(3-hydroxy-1-methylbutyl)barbituric acids
Abstract
The c.d. spectra for 5-alkyl-5-(3-hydroxy-1-methylbutyl)barbituric acids (2) in trifluoroethanol show two Cotton effects in the 230–260 nm region opposite in sign from those of similar compounds lacking a side-chain 3-hydroxygroup.
