A Copper-Catalyzed Synthesis of Functionalized Quinazolines from Isocyanides and Aniline Tri- and Dichloroacetonitrile Adducts through Intramolecular C–H Activation
A novel class of substituted quinazolines were prepared in good yields by a one-pot three-component reaction of isocyanides with adducts of anilines and tri- or dichloroacetonitrile, followed by intramolecular C–H activation, catalyzed by copper(I) iodide with l -proline as a ligand in acetonitrile at room temperature.
