Journal of chromatography, 307(2), 335-342 (1984-05-11)
High-performance liquid chromatography (HPLC) was employed for resolution of enantiomers of chiral ring-substituted 1-phenyl-2- aminopropanes (amphetamines) and 1-phenylethylamine following derivatization with four chiral reagents: (R)-(+)-1-phenylethyl isocyanate ( PEIC ), (-)-alpha-methoxy-alpha-(trifluoromethyl)phenylacetyl chloride ( MTPA X Cl), 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl isothiocyanate ( GITC )

Nature protocols, 2(10), 2451-2458 (2007-10-20)
This protocol details the most commonly used nuclear magnetic resonance (NMR)-based method for deducing the configuration of otherwise unknown stereogenic, secondary carbinol (alcohol) centers (R1R2CHOH (or the analogous amines where OH is replaced by NH2)). This 'Mosher ester analysis' relies
