Abstract

Palladium-catalyzed processes play a vital role in the synthesis of heterocycles. 6 Recently, we reported a palladium-catalyzed intramolecular oxypalladation of phenol derivatives to synthesize 2-methylchromanones. 7 In light of the success of this Wacker-type oxidative cyclization, we turned our attention to a more challenging aza-Wacker oxidative cyclization. 8-9 Compared to the previous report, 7 the unusual 1,5-hydride alkyl to palladium migration is not observed in this aza- ...
