The two new diastereoisomeric chiral auxiliaries (aR,R)-29- Hydroxy-1,19-binaphthyl-2-yl [(3,5-dinitrobenzoyl)amino]- (phenyl)acetate and (aR,S)-29-Hydroxy-1,19-binaphthyl-2-yl [(3,5-dinitrobenzoyl)amino](phenyl)acetate have been synthesised and their efficiency as chiral solvating agents for the determination of the enantiomeric composition of amides and amines has been demonstrated. A conformational study of the two chiral solvating agents (CSAs) by means of NMR and CD spectroscopy is also presented.

Abstract
The two new diastereoisomeric chiral auxiliaries (aR,R)-29- Hydroxy-1,19-binaphthyl-2-yl [(3,5-dinitrobenzoyl)amino]- (phenyl)acetate and (aR,S)-29-Hydroxy-1,19-binaphthyl-2-yl [(3,5-dinitrobenzoyl)amino](phenyl)acetate have been synthesised and their efficiency as chiral solvating agents for the determination of the enantiomeric composition of amides and amines has been demonstrated. A conformational study of the two chiral solvating agents (CSAs) by means of NMR and CD spectroscopy is also presented.File in questo prodotto:
