Asymmetric induction during the aminolysis of 5(4H)-oxazolones from N-benzoyl amino acids was investigated using a series of amino acid esters as amine nucleophiles.The reaction of the oxazolone from N-benzoyl-DL-t-leucine with methyl L-prolinate was found to produce the diastereomeric D-L isomer, almost specifically, under appropriate conditions.
