Primary and secondary amines condense with benzotriazole and glyoxal monoacetal to give N-substituted 1-(benzotriazolyl)-2,2-diethoxyethylamines 4, which with Grignard reagents readily yield the corresponding 2-aminoalkanal diethylacetal 5. These are easily hydrolyzed to produce α-aminoaldehydes 6.
伯胺和仲胺与苯并三唑和乙二醛单乙醛缩合,生成 N-取代的 1-(苯并三唑基)-2,2-二乙氧基乙胺 4,这些乙胺与格氏试剂一起很容易生成相应的 2-氨基烷醛二乙醛 5。这些物质很容易水解生成 δ-氨基醛 6。
