In the title compound, C 19 H 19 NO 3 , formed from enantiomerically pure (+)-(4R,5S)-4-methyl-5-phenyl-2-oxazolidinone and racemic 2-phenylpropanoyl chloride, the two carbonyl groups are oriented anti to each other, and the two methyl groups are oriented anti to each other.
The condensation of (1 R,2S) or (lS,2S)-N,N'-dimethyI-l-phenylpropane-l 2-diamines with aldehydes gives respectively two diastereorneric 2-alkyl-l,3,4-trimethyI-S-phen limidazolidines. At thermodynamical equilibrium the major isomer in the erythro series is this one where t f ! e substituents at pos
