DL-propargyl glycine intermediate and preparation method thereof, and propargyl glycine preparation method based on intermediate

The invention relates to the field of amino acid preparation, in particular to a DL-propargyl glycine intermediate, a preparation method of the DL-propargyl glycine intermediate and a preparation method of propargyl glycine based on the DL-propargyl glycine intermediate. The preparation method of the DL-propargyl glycine intermediate comprises three steps of condensation, saponification and hydrolysis, and then corresponding derivatives can be obtained through a chemical resolution method and an enzyme resolution method respectively. According to the preparation method, the reaction time is shortened; the reaction is more thorough, thepreparation method of DL-propargyl glycine can be obtained through the reaction, two methods for preparing derivatives of D-propargyl glycine and L-propargylglycine are obtained at the same time, the prepared product is high in purity, secondary refining is not needed, the production cost is reduced, and industrial large-scale production is facilitated.
