The use of alpha-amino-epsilon-caprolactam as a resolving agent for N-acetylindoline-2-carboxylic acid and method for preparing optically active N-acetylindoline-2-carboxylic acid

摘要

A resolving agent for N-acetylindoline-2-carboxylic acid, comprising an optically active α-amino-ε-caprolactam gives an optically active N-acetylindoline-2-carboxylic acid in both high yield and high optical purity.
