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.
摘要:一种简便的方法已经被开发出来,通过β-苯酚羟基酮中的羟基促进从酮中构建碳氮双键。值得注意的是,卤代β-苯酚羟基酮可以与胺发生化学选择性反应,生成卤代苯酚亚胺。这种方法适用于某些天然产物,也适用于水基杂胺。该方法毒性低,广泛适用。这种策略通常用于获得芳香胺席夫碱的适度到良好的产率。
