remarkable operational simplicity as it allows the use of benchtop-grade solvents without the need for predrying measures and inert atmosphere protection. Additionally, it demonstrates good functional group compatibility. The photophysical properties of these compounds were also examined, revealing bright fluorescence with high quantum yields.
1,8-二氮杂双环[5.4.0]十一碳-7-烯促进的邻炔基醌甲基化物(由模块化炔丙胺原位生成)级联双环化,用于构建2-芳基-4-羟基苯并[ c ]苯并苯并吡喃开发了-6-ones。这种合成策略提供了显着的操作简单性,因为它允许使用台式级溶剂,无需预干燥措施和惰性气氛保护。此外,它还表现出良好的官能团兼容性。还检查了这些化合物的光物理性质,显示出具有高量子产率的明亮荧光。
