Abstract:
The absolute configuration of chiral secondary alcohols can easily be determined
by derivatization of these alcohols with new chiral derivatizing agents, the hindered acidanthracene
adducts (HAAs), followed by comparison of the 1H NMR chemical shifts of their
diastereomers. Both enantiomers of HAA were synthesized from optically active dimethyl
itaconate-anthracene adducts in moderate overall yield. The (R)- and (S)-1-phenyl-1-ethanol
have been used to validate HAAs, which are explained in terms of deshielding selection by
the protons on the substrate locating at the same side of the aryl group of HAA. As a result,
the effects correspond to ΔδSR values. The absolute configuration assignment can be achieved
using the ΔδSR values of the resulting diastereomers obtained from the NMR data.
