    Abstract: In hydrocarboxylating an alpha-enamide with CO and an organic hydroxyl cpd. to produce an N-acyl-alpha-amino acid ester whose alpha C atom is chiral, the improvement comprises using as the organic hydroxyl cpd. reactant an organic hydroxyl cpd. which also has a chiral C atom that is all L or D, thereby producing a reaction mixt. having no enantiomeric pairs and contg. diastereomeric N-acyl-alpha-amino acid esters having 2 chiral centres, the hydrocarboxylating simultaneously creating (1) the ester, the chirality of the alpha C atom in L, D furn and (2) the second chiral centre in the ester in all L or all D form.
