Cas no 161660-94-2 ((1R,3S)-3-{[(tert-butoxy)carbonyl]amino}cyclopentane-1-carboxylic acid)

(1R,3S)-3-{[(tert-Butoxy)carbonyl]amino}cyclopentane-1-carboxylic acid is a chiral cyclopentane derivative featuring both a Boc-protected amino group and a carboxylic acid functionality. This compound is valuable in organic synthesis and pharmaceutical research due to its stereospecific configuration, which enables precise control over enantioselective reactions. The tert-butoxycarbonyl (Boc) group provides stability under basic conditions while allowing selective deprotection under acidic conditions, making it suitable for stepwise peptide and small-molecule synthesis. The carboxylic acid moiety offers further derivatization potential, facilitating its use as a building block for complex molecular architectures. Its well-defined stereochemistry and bifunctional nature make it particularly useful in medicinal chemistry for the development of bioactive compounds.
