## 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

In the course of systematic study of the chlroptlcal propertles of DNP-c(amino acids, we noted that CD-spectra of DNP-aromatlc amino acids show characterlstlc pattern, which 1s somewhat different from those of Na,Nw-dl-DNPamino aclds1)'2). They have lower intensity and their shorter wavelength band
