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
