What is another name for pyrrolidone-5-carboxylic acid?
Other names: 2-Pyrrolidone-5-carboxylic acid, tert-butyldimethylsilyl ester; tert-Butyl (dimethyl)silyl 5-oxoprolinate Data from NIST Standard Reference Database 69: NIST Chemistry WebBook
Why do stereoisomers of the 2-pyrrolidone-5-carboxylic acid compounds exist?
The 2-pyrrolidone-5-carboxylic acid compounds of the present invention contain an asymmetric carbon atom in the 2-pyrrolidone-5-carboxylic acid moiety, and therefore, stereoisomers of the 2-pyrrolidone-5-carboxylic acid compounds of the present invention exist depending upon the configuration of the asymmetric carbon atom.
