Widely used as a key intermediate in the synthesis of β-lactam antibiotics, particularly carbapenems and penems. Its protected hydroxyl group and defined stereochemistry allow selective reactions in multi-step antibiotic production. The triethylsilyl group acts as a protecting group, enabling controlled deprotection during synthesis. This compound supports the construction of complex antibiotic frameworks with high stereoselectivity, essential for biological activity. Commonly employed in pharmaceutical research and development for novel antimicrobial agents.
