Herein, we report the synthesis and characterization of a series of thioarylmaleimides and their varied propensity toward highly selective domino Diels–Alder (D–A)/rearrangement, D–A/ene/elimination, and D–A/oxidation reactions to give three types of thienyl-fused architectures. Stereochemical assignment was achieved using a combination of nuclear magnetic resonance (NMR) studies, gauge independent atomic
在此,我们报告了一系列硫代芳基马来酰亚胺的合成和表征及其对高选择性多米诺骨牌狄尔斯-阿尔德(D-A)/重排、D-A/烯/消除和D-A/氧化反应的不同倾向,得到三种噻吩基稠合结构的类型。立体化学分配是通过结合核磁共振 (NMR) 研究、规范独立原子轨道 (GIAO) NMR 化学位移计算和 DP4+ 分析来实现的。过渡态计算支持异步协同机制,并为合理化观察到的区域选择性和立体选择性提供支持。
