A novel synthesis method was developed for developing functionalized indolizines. In this reaction, 2-(pyridin-2-yl)acetate derivatives and ,-dimethylenamine ketones were used as substrates. All these processes were enabled by heating a mixture of starting materials in toluene and in the presence of I under air. Cascade reaction resulted in the formation of two bonds and cleavage of one bond in one
开发了一种用于开发功能化中氮茚的新合成方法。在此反应中,2-(吡啶-2-基)乙酸酯衍生物和,-二亚甲基胺酮用作底物。所有这些过程都是通过在空气中在 I 存在下加热甲苯中的起始材料混合物来实现的。级联反应导致一锅中形成两个键并裂解一个键。因此,通过级联反应产生了许多官能化中氮茚。该方案可用于合成功能化不对称2,4-二芳基吡啶。此外,它适用于一锅反应中中氮茚衍生物的组合和平行合成,而不是繁琐的多步反应。
