We have developed a versatile and efficient method for copper-catalyzed synthesis of both 2-amino-4(3H)-quinazolinone and 2-aminoquinazoline derivatives. The protocol uses readily available substituted 2-halobenzoic acids, 2-bromobenzaldehyde, 2-bromophenyl ketones and guanidines as the starting materials, inexpensive copper(I) iodide as the catalyst, and the method has important application values
