## Abstract Enantiopure α‐amino acids were converted to 4‐substituted 2‐aryl‐ and 2‐alkyl‐5(4__H__)‐oxazolones under partial racemization. These nonracemic mixtures were dissolved in CDCl~3~, an equimolar amount of the chiral dirhodium complex $Rh^{\rm (II)}\_{2}$[(__R__)− (+)− MTPA]~4~ (MTPA‐H = M

The absolute configuration of beta-hydroxy-alpha-amino acids was studied by CD exciton chirality method using 7-diethylaminocoumarin-3-carboxylate as a red-shifted chromophore. The CD spectra of bischromophoric derivatives of (S)-serine and (2S,3R)-threonine methyl esters (2 and 7) were compared wit
