Boc-L-Pyroglutamic acid benzyl ester

Boc-L-Pyroglutamic acid benzyl ester

CAS No.: 113400-36-5

A highly stable chiral amino acid derivative, mainly used in peptide drug synthesis, pharmaceutical intermediate R&D, and asymmetric catalysis, serving as a crucial building block for complex chiral drug molecules.

1. Key Intermediate for Peptide Drug Synthesis
The Boc group protects the amino group and the benzyl ester protects the carboxyl group. This dual-protection structure enables precise control of reaction sites in solid-phase peptide synthesis (SPPS), suitable for long-chain and cyclic peptides.

2. Precursor for Anti-HIV and Antitumor Drugs
With its chiral pyrrolidone ring structure, it is widely used as an intermediate for anti-HIV, antitumor, and neurological drugs, especially for synthetic routes requiring benzyl protection.

3. Chiral Ligands and Asymmetric Catalysis
Used as a chiral backbone material to prepare ligands or catalysts for asymmetric catalysis, controlling stereoselectivity and improving the optical purity of chiral drugs.

4. Versatile Building Block in Organic Synthesis
It can construct heterocyclic compounds and complex organic molecules via selective deprotection, coupling, reduction, etc., making it a common intermediate in new drug R&D.
