For the first time it is reported that 1,5-benzothiazepines (1a-e) (Figure I) behave as effective chiral solvating agents (CSA) for NMR enantiomeric excess (ee) determination of different classes of compounds such as alpha-arylalkanoic acids, alpha-hydroxy acids, alkanesulfonic acids, alcohols and 1,5-benzothiazepines. The molecular association between CSA and substrate is explained in terms of N-H and/or O-H hydrogen bonding.
