赤堀氨基酸反应

赤堀氨基酸反应(Akabori amino acid reaction)有两种:
#α-氨基酸在加热时被氧化性糖氧化。

#α-氨基酸及其酯类被钠汞齐在氯化氢的乙醇溶液中还原,生成 α-氨基醛。

There are several Akabori amino acid reactions, which are named after Shirō Akabori (jap. 赤堀 四郎) (1900–1992), a Japanese chemist.

In the first reaction, an α-amino acid is oxidised and undergoes decarboxylation to give an aldehyde at the former α position by heating with oxygen in the presence of a reducing sugar. This reaction is useful for preparing dichlorophthalimido derivatives of peptides for mass spectral analysis.

In the second reaction, an α-amino acid, or an ester of it, is reduced by sodium amalgam and ethanolic HCl to give an α-amino aldehyde. This process is conceptually similar to the Bouveault–Blanc reduction except that it stops at the aldehyde stage rather than reducing the ester all the way to two alcohols.
