α,ω-Diamino acid derivatives, such as lysine and ornithine, were synthesized viaamidocarbonylation (cobalt-catalyzed formation of N-acyl α-amino acid from aldehyde, amide and carbon monoxide) of ω-(phthalimido)alkanals in good yield. The phthalimido group was proved to be intact under the conditions of amidocarbonylation. The hydroformylation-amidocarbonylation of N-phthaloyl-β,γ- and N-phthaloyl-γ

A three-step redox-economical synthesis of α-substituted α-N-phthaloyl aldehydes was developed using Fukuyama reduction from commercially available amino acids. The developed method provided various α-substituted α-N-phthaloyl aldehydes (16 entries) in 29–98 % yields. The developed protocol was reproducible on a large scale.
