Used as a key intermediate in the synthesis of carbapenem antibiotics, which are broad-spectrum beta-lactam antibiotics effective against a wide range of Gram-positive and Gram-negative bacteria, including multidrug-resistant strains. Its structure enables the construction of the core beta-lactam ring system essential for antibacterial activity. The silyl protecting group and allyl ester functionalities allow for selective reactions during stepwise assembly of the final active pharmaceutical ingredient. Commonly employed in controlled environments for the preparation of advanced intermediates in antibiotic development.
