efficient protocol for Ru(II)-catalyzed direct C–H oxygenation of a broad range of flavone and chromone substrates was developed. This convenient and powerful synthetic tool allows for the rapid installation of the hydroxyl group into the flavone, chromone, and other related scaffolds and opens the way for analog synthesis of highly potent Aurora kinase inhibitors. The molecular docking simulations indicate
开发了一种有效的规程,用于Ru(II)催化的各种黄酮和色酮底物的直接CH–H氧合。这种方便而强大的合成工具可将羟基快速安装到黄酮,色酮和其他相关支架中,并为强效Aurora激酶抑制剂的模拟合成开辟了道路。分子对接模拟表明,在5-羟基类黄酮与Ala213之间的铰链区域中,双齿H键结构的形成是显着的结合力,这与实验和计算结果是一致的。
