METHOD OF PRODUCING OPTICALLY ACTIVE 1-AMINO-2-VINYLCYCLOPROPANE CARBOXYLIC ACID ESTER

摘要

An optically active 1-amino-2-vinylcyclopropanecarboxylic acid ester with high optical purity can be obtained by a method of producing an optically active 1-amino-2-vinylcyclopropanecarboxylic acid ester by reacting a 1-amino-2-vinylcyclopropanecarboxylic acid ester with an optically active tartaric acid or an optically active camphorsulfonic acid in a solvent, isolating one diastereomeric salt from the obtained diastereomeric salt mixture and treating the isolated diastereomeric salt with an inorganic acid or a base.
