✦ Synopsis
Benzoylated and benzylated cyclodextrins give rise to non-spectroscopy. Cyclodextrins bearing aromatic substituents at the primary or secondary sites only are more efficient CSAs equivalence in the 1 H-NMR spectra of racemates of 3,5dinitrophenyl derivatives of chiral amines, amino alcohols, compared to exhaustively substituted ones. NMR investigations based on NOE measurements or complexation alcohols, carboxylic acids and amino acids in CDCl 3 solution, suggesting their potential use as CDCl 3 -soluble shift determinations strongly suggest non-inclusive interaction mechanisms for these selector/selectand systems. cyclodextrinic chiral solvating agents (CSAs) in NMR
