Heyns rearrangement for the synthesis of chiral α-amino ketones with readily available substrates. The rearrangement is different from the Heyns rearrangement in that the α-amino ketones were obtained without the shift of the carbonyl group. The key to success is using chiral primary amine as a catalyst by mimicking glucosamine-6-phosphate synthase in catalyzing the efficient Heyns rearrangement in organisms
在此,我们公开了一种基于 Heyns 重排的新型催化不对称串联反应,用于合成具有现成底物的手性 α-氨基酮。该重排与Heyns重排的不同之处在于,在没有羰基移位的情况下获得了α-氨基酮。成功的关键是使用手性伯胺作为催化剂,通过模拟 6-磷酸氨基葡萄糖合酶催化生物体中的有效海恩斯重排。
