Cycloadditions of α-aminonitrile diene
Abstract
Cycloadditions of 2-(N-methylanilino)hexa-2,4-dienenitrile with the dienophiles maleic anhydride, N-phenylmaleimide, benzoquinone, or dimethyl acetylenedicarboxylate led to methyldiarylamines after loss of hydrogen cyanide and oxidative aromatisation.
