## Abstract The chiral phosphorus derivatizing agent (CDA) 1 was prepared from optically pure (S)‐__1,1‐bis‐2‐naphthol__. It was first used in the determination of the enantiomeric excess of chiral alcohols and amines by means of ^31^P NMR spectroscopy. It showed that, for the chiral aromatic alcoh
