and completely regioselective three-component synthesis of highly functionalized pyridines from 1,3-dicarbonyl derivatives and Michael acceptors has been achieved. Activated Michael acceptors, that is, β,γ-unsaturated α-oxo carbonyl derivatives, were utilized, allowing substitution at the 4-position and remarkable functional diversity at the 2-position of the pyridine ring. The scope and limitations
已经实现了由 1,3-二羰基衍生物和迈克尔受体合成高度官能化吡啶的无金属和完全区域选择性的三组分合成。利用活化的迈克尔受体,即 β,γ-不饱和 α-羰基衍生物,允许在吡啶环的 4 位取代和在 2 位显着的功能多样性。公开了这种环境友好的多米诺骨牌反应的范围和局限性,并提供了完整的实验数据,并讨论了机理研究的结果。
