(S)-N-Fmoc-Allylglycine丨CAS 146549-21-5

(S)-N-Fmoc-Allylglycine (CAS 146549-21-5) is a protected amino acid derivative widely used in peptide synthesis and medicinal chemistry. It serves as a key building block in solid-phase peptide synthesis (SPPS), where the Fmoc (9-fluorenylmethoxycarbonyl) group acts as a removable protecting group for the amine functionality. The allyl side chain allows for further chemical modifications, such as cross-coupling reactions, olefin metathesis, or selective deprotection, facilitating the synthesis of complex peptides and peptidomimetics. This compound is particularly valuable in the preparation of modified peptides with enhanced biological activity, stability, or binding affinity. Additionally, it is used in the design of enzyme substrates, structural analogs, and bioactive compounds in pharmaceutical and biochemical research.

The benefits of (S)-N-Fmoc-Allylglycine arise from its structural versatility and stereochemical purity. The (S)-configuration ensures that peptides synthesized with this amino acid maintain the correct chirality, which is critical for biological function. The Fmoc protection strategy provides excellent compatibility with standard SPPS techniques, allowing for efficient stepwise synthesis and easy removal under mild basic conditions without affecting other sensitive groups. The allyl moiety offers a functional handle for orthogonal reactions, enabling selective modifications and the creation of tailored molecular architectures. Furthermore, its chemical stability, high purity, and adaptability make it an indispensable reagent in modern peptide and pharmaceutical chemistry.
