An electrochemical method for the synthesis of quinazoline heterocycles without the need for external oxidants or transition-metal has been developed. In an undivided electrochemical cell, using ammonium iodide as the electrolyte, readily available graphite rods and nickel plates as the anode and cathode, a series of biologically active quinazoline derivatives were efficiently synthesized. This strategy exhibits excellent functional group compatibility, accommodating various substituted benzylamines including electron-donating groups, electron-withdrawing groups, halogens and heterocycles. The protocol was successfully extended to 2-amino-2-arylacetic acids as substrates, with 2-amino-2-phenylacetic acid affording the corres- ponding product in 45%~98% yields under optimized conditions.
