Reaction of 4,6-Di-tert-butyl-3-nitrocyclohexa-3,5-diene-1,2-dione with Secondary Amines

Abstract

The reaction of 4,6-di-tert-butyl-3-nitrocyclohexa-3,5-diene-1,2-dione with secondary amines (piperidine, morpholine, 1-methylpiperazine) in isopropanol involves Michael addition and ANRORC and forms a mixture of products. The resulting compounds were characterized by IR and 1H and 13C NMR spectroscopy, and elemental analysis. The molecular structures of 3-nitrocyclohexa-3-ene-1,2-dione and cyclopenta-1,3-diene derivatives were established by X-ray diffraction analysis.
