Used in pharmaceutical research as a chiral intermediate for synthesizing bioactive molecules, particularly in the development of central nervous system agents. Its oxazoline core and isoquinoline moiety contribute to binding selectivity in receptor-targeted drugs. Commonly employed in asymmetric synthesis due to the R-configuration, enabling high enantiomeric purity in final drug compounds. Also explored in the design of enzyme inhibitors, especially for kinases and proteases involved in inflammatory and oncological pathways.
