Palladium-Catalyzed Dehydrogenative β’-Arylation of β-Keto Esters under Aerobic Conditions: Interplay of Metal and Brønsted Acids

2012

The Bronsted aids: The first dehydrogenative arylation of β-keto esters with arenes under ambient aerobic conditions is described. Under a Pd(II)/Bronsted acid co-catalytic system, regioselective arylations with alkoxylated arenes and phenols were achieved in good yields, even in gram-scale conditions.

Palladium-catalyzed dehydrogenative β'-functionalization of β-keto esters with indoles at room temperature.

2012

The dehydrogenative β′-functionalization of α-substituted β-keto esters with indoles proceeds with high regioselectivities (C3-selective for the indole partner and β′-selective for the β-keto ester) and good yields under mild palladium catalysis at room temperature with a variety of oxidants. Two possible mechanisms involving either late or early involvement of indole are presented.
