A simple and efficient Pd-catalyzed method for the C2-acylation of indoles is described. Less toxic, stable, and commercially available toluene derivatives were used as acyl sources, with tert-butylhydroperoxide (TBHP) as oxidant and pivalic acid as additive, providing moderate to good yields.
描述了一种简单有效的Pd催化吲哚C2-酰化的方法。毒性较小,稳定且可商购的甲苯衍生物用作酰基源,叔丁基氢过氧化物(TBHP)作为氧化剂,新戊酸作为添加剂,提供中等至良好的收率。
