Cas no 63399-77-9 ((2R)-2-methylpyrrolidine-2-carboxylic acid)

(2R)-2-Methylpyrrolidine-2-carboxylic acid is a chiral non-proteinogenic amino acid featuring a pyrrolidine ring with a methyl substituent at the 2-position. Its stereospecific (R)-configuration makes it a valuable building block in asymmetric synthesis and pharmaceutical applications, particularly in the design of peptidomimetics and bioactive compounds. The rigid pyrrolidine scaffold enhances conformational control, while the carboxylic acid functionality allows for further derivatization. This compound is useful in medicinal chemistry for developing enzyme inhibitors or receptor modulators due to its structural similarity to proline. High enantiomeric purity ensures reproducibility in research and industrial processes. Suitable for use under inert conditions to preserve stability.
