Procedure

According to a particular variant of embodiment of this synthesis process, 1-benzyl-3-pyrrolidinone is treated with an ammoniacal solution of ammonium chloride and of potassium cyanide to obtain (±)-3-amino-1-benzyl-3-cyanopyrrolidine. This compound is then converted by acid or basic hydrolysis to (±)-3-amino-1-benzyl-3-pyrrolidinecarboxylic acid, and lastly a reduction with hydrogen, preferably a catalytic hydrogenolysis, is carried out to obtain (±)-3-amino-3-pyrrolidinecarboxylic acid or (±)-cucurbitine.
