还原胺化是有机合成中的重要反应, 即醛和酮在适当还原剂作用下与伯胺或仲胺制备仲、叔胺. 汉斯酯1,4-二氢吡啶衍生物(HEH)作为仿生有机还原剂已被用于α,β-不饱和羰基化合物、缺电子的共轭烯烃和亚胺的选择性还原以及还原胺化等重要的有机反应中. 以HEH为还原剂, 7-氨基-4-甲基香豆素与常见的醛为模型来探索通过还原胺化反应标记醛类化合物的可行性, 共得到16个还原胺化产物, 其中13个化合物未见文献报道.

Reductive amination is an important reaction in organic synthesis. Aldehyde and ketone can react with primary and secondary amine in the presence of appropriate reducing reagent to afford secondary and tertiary amine. Hantzsch ester 1,4-dihydropyridine (HEH) is employed in the selective reduction and reductive amination of α,β-unsaturated carbonyl compounds, electron-deficient conjugate alkene and imine as a biomimetic organic reductant. In this paper, the possibility of labeling aldehyde by reductive amination using HEH as reductant, 7-amino-4-methylcoumarin and aldehydes as models was studied. Sixteen products were synthesized, among them, thirteen compounds were not reported in the literature.

Key words: Hantzsch ester 1,4-dihydropyridine, reductive amination, coumarin, aldehyde, label
