Description
tert-Butyl (S)-(-)-lactate is a chiral building block featuring a stereodefined lactate ester with a bulky tert-butyl group. This configuration imparts enhanced stability and resistance to racemization, enabling reliable asymmetric synthesis. The molecule integrates seamlessly into complex molecular architectures requiring precise stereocontrol.
Application
tert-Butyl (S)-(-)-lactate serves as a stable, bench-ready chiral building block for asymmetric synthesis, enabling efficient access to enantioselective intermediates. Its ester functionality tolerates a range of reaction conditions and facilitates straightforward deprotection to the corresponding (S)-lactic acid derivative. Widely used in medicinal chemistry and catalyst design, it functions as a key synthon for biologically relevant scaffolds.
