from abundant and biologically important hydroxyflavones were used to synthesize a series of functionalized flavones through versatile palladium-catalyzed cross-coupling reactions. A Pd(OAc)2/2-[2-(dicyclohexylphosphino)phenyl]-1-methyl-1H-indole system effectively catalyzed the reactions of a broad range of tosyloxy- and mesyloxyflavones as electrophilic coupling partners with various nucleophiles to
来源于丰富且具有生物学重要性的羟基黄酮的甲苯磺酰氧基和甲磺酰氧基黄酮被用于通过多功能的钯催化交叉偶联反应合成一系列功能化黄酮。Pd(OAc)2/2-[2-(dicyclohexylphosphino)phenyl]-1-methyl-1H-indole 系统有效地催化了广泛的甲苯磺酰氧基和甲磺酰氧基黄酮作为亲电偶联伙伴与各种亲核试剂的反应,得到相应的产品良率高。成功使用了低至 0.1 mol% Pd 的催化剂负载量。重要的是,我们证明该协议在合成潜在的基于 chromen-4-one 的 DNA 依赖性蛋白激酶抑制剂的类似物方面提供了显着提高的效率。
