Objects of the present invention are to provide an industrially applicable method for producing an optically active α-amino acid in high yield and in a highly enantioselective manner, to provide a simple production method of an optically active α,α-disubstituted α-amino acid, and to provide an intermediate useful for the above production methods of an optically active α-amino acid and an optically active α,α-disubstituted α-amino acid.
The present invention provides a production method of an optically active α-amino acid or a salt thereof, the production method comprising introducing a substituent into the α carbon in the α-amino acid moiety of a metal complex represented by the following Formula (1):
by an alkylation reaction, an aldol reaction, the Michael reaction, or the Mannich reaction, and releasing an optically pure α-amino acid enantiomer or a salt thereof by acid decomposition of the metal complex.
本发明的目的是提供一种在高产率和高对映选择性的方式下生产光学活性α-氨基酸的工业上适用的方法,提供一种简单的生产方法,用于光学活性α,α-二取代的α-氨基酸,并提供一种用于上述光学活性α-氨基酸和光学活性α,α-二取代的α-氨基酸生产方法的中间体。本发明提供了一种光学活性α-氨基酸或其盐的生产方法,该生产方法包括通过烷基化反应、醛醇反应、迈克尔反应或曼尼希反应将取代基引入以下式(1)所表示的金属配合物的α-氨基酸基团的α碳中,并通过酸分解金属配合物释放光学纯α-氨基酸对映体或其盐。
