The corresponding chiral lithium amide is used as base for the enantioselective deprotonation of ketones. (−)-Bis(S)-1-phenylethylamine hydrochloride can be used: To prepare phosphoramidite (Feringa) ligand named (R)-2,2′-binaphthoyl-(S,S)-di-(1-phenylethyl)aminoylphosphine. As a chiral amphiphilic cation to encapsulate polyoxometalates, which act as supramolecular assemblies employed in the asymmetric oxidation of sulfides. As a chiral shift agent in the determination of enantiomeric purity of tris(tetrachlorobenzenediolato) phosphate(V) anion using 31P NMR.
