===For the synthesis of heterocycles===
Catalytic amounts of aqueous CAN allow the efficient synthesis of [[quinoxaline]] derivatives. Quinoxalines are known for their applications as dyes, [[organic semiconductor]]s, and DNA cleaving agents. These derivatives are also components in antibiotics such as [[echinomycin]] and [[actinomycin]]. The CAN-catalyzed three-component reaction between [[aniline]]s and [[alkyl vinyl ether]]s provides an efficient entry into 2-methyl-1,2,3,4-tetrahydroquinolines and the corresponding [[quinoline]]s obtained by their [[aromatization]].
