transformation relies on an electronically differentiated Lewis base catalyst, which is uniquely capable of promoting a reductive aldol reaction of α,α-disubstituted and α,α,β-trisubstituted enones. This approach provides a valuable synthetic alternative for carbon–carbon bond formation in complex molecular settings due to its orthogonal reactivity compared to that of traditional aldol reactions. Based on this
描述了有效构建带有α-季碳中心的β-羟基内酯和内酰胺的合成方法。该转化依赖于电子分化的路易斯碱催化剂,该催化剂独特地能够促进α,α-二取代的烯醇和α,α,β-三取代的烯酮的还原性羟醛反应。与传统的醛醇缩合反应相比,这种方法具有正交反应性,因此为复杂分子设置中的碳-碳键形成提供了一种有价值的合成方法。基于本文所述的方法,带有α-季碳中心的内酯,内酰胺和吗啉酰胺的产率可达85%和50:1 dr。
