Two synthetic routes to bis-armed-alpha-amino acid derivatives are described. The first route involves alkylation of dibromo derivatives with ethyl isocyanoacetate under phase-transfer catalysis (PTC) conditions. The second route uses a palladium-mediated Suzuki-Miyaura cross-coupling reaction between a DL-4-boronophenylalanine derivative and aromatic
