    摘要: 1-Amino-2-vinylcyclopropanecarboxylic acid ester, which is useful as a synthetic intermediate of pharmaceuticals, can be prodced by a process of producing 1-amino-2-vinylcyclopropanecarboxylic acid ester represented by formula (4):

    comprising a step of hydrolysis of an optically active 1-N-(arylmethylene)amino-2-vinylcyclopropanecarboxylic acid ester represented by formula (3):

    which is obtained by reacting an N-(arylmethylene)glycine ester represented by formula (1):

    with a compound represented by formula (2):

    in the presence of a base and an optically active quaternary ammonium salt.
