Abstract: PROBLEM TO BE SOLVED: To provide the synthetic method of a β-lactam in the presence of high-temperature and high-pressure water, and a manufacturing method of the β lactam. SOLUTION: This synthetic method of the β-lactam is characterized in that the β-lactam is synthesized by reacting a β-amino acid in the presence of high- temperature and high-pressure water. In this case, characteristically, β-lactam is rapidly synthesized by cyclizing the β-amino acid under the condition that the water temperature is 200 deg.C or higher and the water pressure is 10 MPa or higher. The manufacturing method of the β-lactam is characterized in that the β-lactam is synthesized by reacting the β-amino acid in the presence of the high-temperature and high-pressure water and then separated and purified with a separating agent for column separation.

Abstract: PROBLEM TO BE SOLVED: To improve a method for closing a ring of an amino acid for producing a ring closure compound used for an intermediate for producing a medicine or a reagent intermediate from the amino acid, improving the yield and purity of the product, reducing its reacting time, not requiring a catalyst and not generating byproducts. SOLUTION: This method for closing the ring of the amino acid is provided by bringing high temperature and high pressure water at 100-400 deg.C temperature and 5-100 MPa pressure in contact with the amino acid for dehydrating the amino acid to perform the ring closure of the amino acid.
