✦ Synopsis

Chiral Recognition of Amino Alcohols by 1 H and 13 C NMR Spectroscopy Using Binaphthyl Derivatives as Chiral Solvating Agents.

-Different signals in the spectra are doubled in dependence on the substrate as well as the agent. In the 1 H NMR spectra mainly the CH 3 N signal is a useful indicator in observing the effect of chiral discrimination. Only in case of (I) remarkable splittings for H-1 and H-2 are observed. The largest shift differences shows the host-guest pair (±)-(I)/(+)-(VIa). The splittings found in (II) and (III) are essentially smaller. Only low shift differences are observed for the non-cyclic compound (V). -(KOY, C.;
