Abstract/OtherAbstract:
|
Selective formation of 2H-2-imidazolines and 2-substituted oxazoles by using a multicomponent reaction of amines, either aldehydes or ketones, and alpha-acidic isocyano amides or esters is described. By selecting the appropriate solvent, Ag(I) or Cu(I) catalyst, or by employing a weak Brønsted acid, the product formation can be fully controlled and directed quantitatively to the desired heterocyclic scaffold. The described experimental procedures not only significantly increase the scope of compatible inputs for this complexity-generating three-component reaction, but also allow for considerable chemical diversity: At least four diversity points in two distinct scaffolds can be exploited in this way. |
