A transition-metal-free formal (4 + 2) cycloaddition for the direct assembly of acridone derivatives has been developed from simple and easily accessible -aminobenzamides and 2-(trimethylsilyl)aryl triflates. The base played an important role in the selective controlled synthesis of -H and -aryl acridones. A preliminary study on the fluorescence properties of -aryl acridones demonstrated that they could be used as fluorescent materials with a broad emission range.
一种无过渡金属的形式（4 + 2）环加成反应，用于直接组装吖啶酮衍生物，是由简单易得的 -氨基苯甲酰胺和 2-（三甲基硅基）芳基三氟甲磺酸酯发展而来的。碱在 -H 和 -芳基吖啶酮的选择性控制合成中发挥了重要作用。对 -芳基吖啶酮荧光性质的初步研究表明，它们可用作具有宽发射范围的荧光材料。
