Iodine-mediated electrochemical C(sp3)–H cyclization: the synthesis of quinazolinone-fused N-heterocycles

An efficient iodine-mediated electrochemical C(sp3)-H cyclization was developed under mild condition. A variety of functionalized quinazolinone-fused N-heterocycles can be obtained with good to excellent yields by virtue of this method. The reaction features broad substrate scope, scalability, metal-free and chemical oxidant-free.
