This chemical is primarily used in peptide synthesis as a protected form of aspartic acid. The Boc (tert-butyloxycarbonyl) group protects the amino group, while the OAll (allyl ester) group protects the carboxyl group, allowing selective deprotection during the synthesis process. It is particularly valuable in solid-phase peptide synthesis (SPPS) where controlled deprotection and coupling steps are essential. The allyl ester group can be removed under mild conditions using palladium catalysts, making it suitable for synthesizing complex peptides without disrupting other sensitive functional groups. Its application extends to the production of bioactive peptides, pharmaceuticals, and research compounds where precise control over peptide chain assembly is critical.
