Pd(II)‐Catalyzed Decarboxylative Acylation of Phenylacetamides with α‐Oxocarboxylic Acids via C—H Bond Activation.

A palladium-catalyzed decarboxylative acylation of phenylacetamides with α-oxocarboxylic acids via C–H bond activation is described. This protocol provides efficient access to a range of ortho-acyl phenylacetamides, which can be easily converted to 3-isochromanone derivatives.
