A novel and convenient strategy toward caprolactam and butyrolactam derived phthalimide and amide scaffolds has been fulfilled through the palladium-catalyzedcarbonylativecoupling in a one-pot one step manner. The nucleophilicity of DBU and DBN was applied to the carbonylation reaction for the first time and followed by hydrolysis leading to the ring opening reaction of DBU and DBN. It should be
