Beschreibung

Allgemeine Beschreibung

The (R)- and (S)-isomers are chiral derivatizing agents for NMR determination of enantiomeric purity of α-deuterated carboxylic acids, alcohols, and amines.

Anwendung

(R)-(-)-O-Acetylmandelic acid may be used as a precursor to prepare a chiral diamine, which is an intermediate to prepare Utenone A. It may also be used to prepare ethyl (2′R)-2′-acetoxy-2′-phenylethanoate.
