3-Methyl indanones are key synthetic building blocks for a variety of natural and useful synthetic compounds. Their synthesis is exceedingly difficult. Herein, we described a palladium (II) mediated intramolecular one-pot redox-relay cyclization of aromatic homoallylic alcohols to cyclic keto compounds. This catalytic system enabled direct conversion of homoallylic alcohols to corresponding indanones (3
3-甲基茚满酮是各种天然和有用的合成化合物的关键合成构件。它们的合成极其困难。在此,我们描述了钯(II)介导的芳香族高烯丙醇分子内一锅氧化还原中继环化成环状酮化合物。该催化系统能够将高烯丙醇直接转化为相应的茚满酮(3-甲基-1-茚满酮)。通过烯丙基溴化镁与相应的芳香醛反应合成高烯丙醇。优化后的反应产率高达 88% 3-甲基茚满酮。我们的发现使我们能够为这一一锅反应设计出一种合理的机制。 图形概要
