The regiospecific C-2-H arylation of N-3-substituted quinazolin-4(3H)-ones with a wide range of aryl or (hetero)aryl halides under microwave irradiation was studied. A ligand-dependent palladium/copper bicatalytic system was developed and allowed direct c

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 obtained by photocatalytic radical processes, indicating complementary reactivities in radical processes. The electrochemical reaction pathways were fully revealed by density functional theory-based investigations.
Synthesis of quinazolin-4(3H)-ones via electrochemical decarboxylative cyclization of α?keto acids with 2-aminobenzamides

Herein, an environmentally benign electrochemical protocol has been disclosed for the synthesis of quinazolin-4(3H)-one derivatives from readily available α?keto acids and 2-aminobenzamides. This decarboxylative cyclization process proceeds conveniently in the absence of any homogeneous metal catalysts, bases, or external oxidants. This protocol also features CO2 by-products, mild reaction conditions (room temperature and air atmosphere), and a wide variety of substrate scope, including an array of 2,3-disubstituted quinazolinone products.
