In present work, we have reported the synthesis and characterisation of novel hexahydrospiro[indoline-3,3′-pyrrolizine]-2-one derivatives in good to excellent yields via [3+2] cycloaddtion reaction in regioselective manner. These compounds were synthesized via multicomponent reaction of substituted 3-cinnamoyl-4-hydroxy-6-methyl-2H-pyran-2-one, isatin, L-proline at room temperature. All the synthesized
在目前的工作中,我们报道了通过区域选择性方式的[3+2]环加成反应以良好至优异的收率合成和表征了新型六氢螺[indoline-3,3'-pyrrolizine]-2-one衍生物。这些化合物是通过取代的3-肉桂酰基-4-羟基-6-甲基-2H-吡喃-2-酮、靛红、L-脯氨酸在室温下多组分反应合成的。所有合成的六氢螺分子均通过 1H 和 13C NMR、红外光谱、质谱和元素分析进行了表征。合成分子的区域选择性也可以根据二级轨道相互作用来解释。开发了一种简单易行的方法,这在合成化学中具有非常重要的意义。
