A general synthetic route to synthesis of N-cyclohexyl-3-aryl-quinoxaline-2-amines has been developed using
ZnO nanoparticles under mild conditions. The multi-component reactions of aldehydes, o-phenylenediamine and cyclohexyl
isocyanide were carried out to afford some N-cyclohexyl-3-aryl-quinoxaline-2-amines derivatives. The present approach
offers several advantages such as high yields, environmentally benign, easy purification, recovery and reusability
of the catalyst.
