Selective Hydrogenation of Aromatic Aminoketones by Pd/C Catalysis
摘要:
We report an alternative hydrogenation of aromatic aminoketones by heterogeneous catalyst of palladium on carbon (Pd/C) in which nitro, in particular carbonyl groups in the ketones, could be selectively transformed to corresponding amino ketone, secondary alcohol, or methylene compound.

An operationally simple and efficient protocol for the transformation of carbonyl compounds to tertiary amines with various secondary amine-boranes is reported. The reaction proceeds at room temperature and requires a short reaction time under mild conditions. The reaction encompasses a broad substrate scope and furnishes good-to-excellent yields of the amines in a chemoselective fashion.
Provided herein are compounds which are useful as cooling sensation compounds.
