Abstract
A facile methodology has been developed to build carbon nitrogen double bond from ketones
promoted by the hydroxyl groups in β-phenol hydroxy ketone. It is noteworthy that the halogenated
β-phenol hydroxy ketone can chemoselectively react with the amine to afford halogenated phenol
imine. It is suitable for certain natural products and also suitable for water-based heteroamines. The
method possesses low toxicity and is widely applicable. This strategy is usually used to obtain moderate
to good yields of aromatic amine Schiff base.
Keywords:
Schiff base, low toxicity synthesis, widely applicable, β-phenol hydroxy ketone, amines, organic chemistry.
