A simple method has been developed for the synthesis of 3-aryl quinoxalin-2-one derivatives through an oxidative cross-coupling of arylboronicacids with quinoxalin-2-ones using a readily available oxidant Mn(III) acetate dihydrate. This method provides 3-aryl quinoxalin-2-one scaffolds with a broad substrate scope.

An efficient visible-light-induced CH arylation of quinoxalin-2(1H)-ones in H2O is developed, which has the advantages of mild reaction conditions, environmental friendliness and good functional group tolerance. This strategy provides a simple operation method to access various 3-aryl quinoxalin-2(1H)-ones in moderate to good yields.

We previously identified phenylquinoxalinone CFTRact-J027 (4) as a cysticfibrosistransmembraneconductanceregulator (CFTR) activator with an EC50 of ∼200 nM and demonstrated its therapeutic efficacy in mouse models of constipation. Here, structure–activity studies were done on 36 synthesized phenylquinoxalinone analogs to identify compounds with improved potency and altered metabolic stability.
