A process for efficiently and industrially advantageously producing an N- formylamino acid by reacting an amino acid or its salt with formamide and/or methyl formate in the presence of a base. A process for efficiently and industrially advantageously producing N-formyl-.alpha.-aspartylphenylalanine methyl ester, which is a precursor of aspartame, by an enzymatic fusion reaction of N-formylaspartic acid with phenylalanine methyl ester wherein the concentration of N-formylaspartic acid is specified or the reaction is carried out in the presence of a trialkyl phosphate. A process for efficiently and industrially advantageously producing N-formyl-.alpha.-aspartylphenylalanine methyl ester having a high purity by adjusting the pH value of a phenylalanine methyl ester adduct of N-formyl-.alpha.-aspartylphenylalanine methyl ester.

Procédé de production efficace et industriellement avantageuse d'acide N-formylamino qui consiste à faire réagir un acide aminé ou ses sels avec du formamide et / ou du méthanoate de méthyle en présence d'une base. La présente invention concerne également un procédé permettant de produire de manière efficace et industriellement avantageuse du méthyle ester de N-formyl-.alpha.-aspartylphénylalanine qui est un précurseur de l'aspartame, par une réaction de fusion enzymatique d'acide N-formylaspartique avec du méthyle ester de phénylalanine, la concentration d'acide N-formylaspartique étant spécifiée ou la réaction étant effectuée en présence de trialkyle phosphate. La présente invention concerne encore un procédé permettant de produire de manière efficace et industriellement avantageuse du méthyle ester de N-formyl-.alpha.-aspartylphénylalanine hautement pur par ajustement de la valeur pH d'un produit d'addition méthyle ester de phénylalanine de méthyle ester de N-formyl-.alpha.-aspartylphénylalanine.
