Boc-alpha-phosphonoglycine trimethyl ester

Boc-α-phosphonoglycine trimethyl ester (CAS 89524-98-1) is a strategically protected phosphonate amino acid derivative optimized for peptide mimetic synthesis and enzyme inhibitor development. This molecule features three orthogonal functional elements: a Boc (tert-butoxycarbonyl) protecting group enabling acid-labile amine deprotection under mild conditions, an α-phosphonate moiety that mimics phosphate transition states with superior metabolic stability compared to natural phosphates, and a trimethyl ester configuration that enhances lipophilicity for improved cellular uptake. The phosphonate group—resistant to phosphatase-mediated hydrolysis while maintaining key hydrogen-bonding geometry—positions this intermediate as a versatile scaffold for protease inhibitor design, prodrug strategies, and phosphonopeptide therapeutics targeting metalloenzymes or kinase pathways. Manufactured with purity ≥98% under controlled conditions, it supports medicinal chemistry programs where phosphate mimicry combined with orthogonal protection is essential for structure-activity relationship studies.
