In the process of hydrocarboxylating an α-enamide with CO and H₂O or an organic hydroxyl compound to produce an N-acyl-α-amino acid or ester, respectively, the improvement comprising using as the α-enamide reactant, an α-enamide which has a chiral center that is essentially all L or D, thereby producing a reaction mixture containing diastereomeric N-acyl-α-amino acids or esters having two chiral centers, said mixture having essentially no enantiomeric pairs.
在用CO和H₂O或有机羟基化合物水解氢羧化α-烯酰胺以产生N-酰基-α-氨基酸或酯的过程中,改进包括使用α-烯酰胺反应物,该反应物具有基本全部为L或D的手性中心,从而产生含有两个手性中心的非对映异构的N-酰基-α-氨基酸或酯的反应混合物,该混合物基本上不含对映异构对。
