Use of Diketopiperazines for Determining Absolute Configurations of α-Substituted Serines by 1H-NMR Spectroscopy
摘要:
A chiral alpha-substituted serine of interest was transformed into both of the corresponding diastereomers of diketopiperazines utilizing L- and D-phenylalanine methyl ester hydrochloride. The absolute configuration of the original chiral alpha-substituted serine was determined by H-1-NMR analyses of the resulting diastereomers.
