A palladium-catalyzed intramolecular CH acylation of indole with thioester is described, providing a direct and effective approach for the synthesis of the biologically active indole-indolone scaffolds. The method obviates the need for the prefunctionalized starting materials including organometallic reagents, alkyl halides, and NHP esters in previous metal-catalyzed cross-coupling reaction with thioester
描述了钯用硫酯酯催化的吲哚的分子内C H酰化,为合成具有生物活性的吲哚-吲哚酮骨架提供了直接而有效的方法。该方法消除了在先前的金属催化的与硫酯的交叉偶联反应中对包括有机金属试剂,烷基卤化物和NHP酯在内的预官能化原料的需要。带有敏感卤素基团的底物在反应中是相容的,为进一步的结构修饰留有功能。
