Replacement of the core heterocycle of a defined series of chromen-4-one DNA-PK inhibitors by the isomeric chromen-2-one (coumarin) and isochromen-1-one (isocoumarin) scaffolds was investigated. Structure-activity relationships for DNA-PK inhibition were broadly consistent, albeit with a reduction of potency compared with the parent chromenone. (C) 2010 Elsevier Ltd. All rights reserved.

2-Arylacetamides as Versatile Precursors for 3-Aminoisocoumarin and Homophthalimide Derivatives: Palladium-Catalyzed Cascade Double Carbonylation Reactions
The synthesis of biologically relevant homophthalimide and 3‐aminoisocoumarin nuclei via palladium‐catalyzed carbonylation of 2‐(2‐iodoaryl)acetamides has been developed. The degree of N‐substitution on the starting amide substrate dictates whether C−N or C−O coupling takes place in the final step of the catalytic cycle giving rise to each type of heterocycle. The introduction of a second C−halogen
