A novel palladium-catalyzedoxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronicacids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.

Electrochemistry has recently emerged as a sustainable approach for efficiently generating radical intermediates utilizing eco-friendly electric energy. An electrochemical process was developed to transform 1,2,4-oxadiazolines under mild conditions. The electrochemical N–O bond cleavage at a controlled oxidation potential led to the selective synthesis of quinazolinone derivatives that could not be
