In this Communication, we describe the construction of chiral α,β-unsaturated δ-lactams, widely used as pharmacophores, in high yields and excellent enantioselectivities using an oxidative relay Heck arylation reaction. This strategy also allows facile access to 7-substituted α,β-unsaturated ε-lactam products and δ-lactams containing a tetrasubstituted nitrogen-bearing stereocenter.
在本通讯中,我们描述了使用氧化中继 Heck 芳基化反应以高产率和优异的对映选择性构建广泛用作药效团的手性 α,β-不饱和 δ-内酰胺。该策略还可以轻松获得7-取代的α,β-不饱和ε-内酰胺产物和含有四取代的含氮立构中心的δ-内酰胺。
