Boc-L-aspartic Acid 4-benzyl Ester丨CAS 7536-58-5

Boc-L-aspartic acid 4-benzyl ester (CAS 7536-58-5) is an important intermediate in peptide synthesis and pharmaceutical chemistry. It is used in the preparation of peptides, peptidomimetics, and bioactive molecules where L-aspartic acid serves as a key amino acid component. The compound's dual protection strategy-Boc (tert-butoxycarbonyl) on the amino group and benzyl ester on the side-chain carboxyl group-allows for selective deprotection and stepwise coupling during solid-phase or solution-phase synthesis. It finds applications in synthesizing therapeutic peptides, enzyme inhibitors, and fine chemicals, as well as in research focused on developing new drugs and biochemical probes.

The main advantages of Boc-L-aspartic acid 4-benzyl ester include its excellent stability, controlled reactivity, and compatibility with common peptide coupling reagents. The Boc group provides mild acid-labile protection, allowing clean removal without racemization, while the benzyl ester ensures protection of the carboxylic side chain during peptide assembly. These protective features facilitate efficient synthesis with high yield and purity, reducing byproducts and simplifying purification steps. Moreover, its versatility allows for easy integration into automated peptide synthesizers and scalable pharmaceutical production processes.
