multicomponent methods for the synthesis of benzannulated dihydroindolizines based on quinoline or isoquinoline, malononitrile, aromatic aldehydes and α-halomethylcarbonyl compounds were developed. Several alternative protocols of using the reactants were studied, starting with separate generation of two most probable intermediates and ending with the four-component condensation of all reactants. The scope
开发了用于合成基于喹啉或异喹啉、丙二腈、芳香醛和 α-卤代甲基羰基化合物的苯并环化二氢茚茚的便捷多组分方法。研究了使用反应物的几种替代方案,从单独生成两种最可能的中间体开始,并以所有反应物的四组分缩合结束。发现这些方法的适用范围取决于所使用的初始化合物。该反应具有高度立体选择性,主要形成一种可能的异构体。
