NMR analysis of chiral alcohols and amines using readily available enantiopure MPA (α-methoxy-α-phenylacetic acid) and MTPA (α-methoxy-α-trifluoromethylphenylacetic acid) as chiralderivatizingagents. The procedure requires less than 5 min (including sample preparation time) for analysis using routine NMR hardware and allows accurate measurements for <0.01 mg of the sample of chiral compounds.
