The Michaeladdition of indoles to electron‐deficient nitroolefins was effectively catalyzed by an ionic liquid‐coordinated ytterbium(III) sulfonate catalyst. The recycling procedure of the catalyst was very simple without extraction with water, and the catalyst was reused for five times without any loss of its catalytic activity. Furthermore, to demonstrate the application of this methodology, the

Abstract 4-(p-methoxyphenyl)-β-carboline was prepared in four steps from indole. The key step involved palladium-catalyzed dehydrogenation of a dihydro-β-carboline dichlorophosphinic acid salt. The success of the dehydrogenation was found to depend on the catalyst support.
