α,ω-Diamino acid derivatives, such as lysine and ornithine, were synthesized via amidocarbonylation (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
α,ω-二氨基酸衍生物,如赖氨酸和鸟氨酸,是通过 ω-(邻苯二甲酰亚胺)链烷醛的酰胺羰基化(钴催化从醛、酰胺和一氧化碳形成 N-酰基 α-氨基酸)合成的。证明邻苯二甲酰亚胺基团在酰胺羰基化条件下是完整的。N-邻苯二甲酰-β,γ-和N-邻苯二甲酰-γ,δ-不饱和胺的加氢甲酰化-酰胺羰基化反应进行得非常好,得到具有良好选择性的α,ω-二氨基酸衍生物。α-N-酰基-ω-N-邻苯二甲酰基α,ω-二氨基酸的选择性脱保护是通过使用肼作为N-邻苯二甲酰基和氨酰化酶作为N-乙酰基来实现的,以提供具有旋光活性的α,ω-二氨基酸,分别。
