sequential arylation–allylation of o-bromoanilides and leads to the construction of oxindoles bearing a full carbon quaternary center. The cheap triphenylphosphine was proved to be a highly effective ligand for this one pot transformation. On the basis of this new method, esermethole and its analogues were synthesized.
在这项工作中,开发了通向吡咯并吲哚啉生物碱合成的通用且灵活的合成途径。这种新的策略以邻位溴代苯胺的钯介导的连续芳基化-烯丙基化为特征,并导致了带有完整碳四元中心的羟吲哚的构建。便宜的三苯膦被证明是这种一锅转化的高效配体。在这种新方法的基础上,乙二胺 并合成了类似物。
