Efficient Synthesis of a Phosphinate Bis-Amino Acid and Its Use in the Construction of Amphiphilic Peptides
摘要:
A new amphiphilic bis-amino acid has been designed and its convergent, asymmetric synthesis achieved in differentially protected form. A convenient preparation of iodophenylalanine, a generally useful starting material, is disclosed. Sequential palladium-catalyzed couplings of aryl iodides to phosphinate lead directly to the target protected bis-amino acid. Controlled peptide coupling of the new bis-amino acid is also demonstrated.
