The objective of the present invention is to provide a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative with high yield and high optical purity using a safe material available at low cost. In addition, the objective of the present invention is to provide a method for safely-obtaining an optically active vinylcyclopropaneamino acid with high optical purity at low cost. The problems can be solved by a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative, which method contains the step of reacting a racemic vinylcyclopropanecarboxylic acid derivative with an optically active amine compound, to obtain a diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative-amine compound. In addition, it is possible to obtain a vinylcyclopropaneamino acid by deriving the vinylcyclopropaneamino acid from thus obtained diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative-amine compound.
本发明的目的是提供一种方法,使用成本低廉的安全材料高产高光学纯度地获得光学活性的乙烯基环丙烷羧酸衍生物。此外,本发明的目的还是提供一种以低成本安全地获得高光学纯度的光学活性乙烯基环丙烷氨基酸的方法。这些问题可以通过一种方法来解决,该方法包含将外消旋的乙烯基环丙烷羧酸衍生物与光学活性胺化合物反应,以获得光学活性乙烯基环丙烷羧酸衍生物-胺化合物的对映异构体盐。此外,可以通过从所获得的光学活性乙烯基环丙烷羧酸衍生物-胺化合物的对映异构体盐中推导出乙烯基环丙烷氨基酸。
