Employing camphor- and nopinone-derived monooximes, two classes of terpene-fused pyrazine derivatives were synthesized. Besides being solvent-free, the described one-step procedure can be directed towards terpene-fused imidazole or pyrazine derivatives. Whereas the reaction worked well with arylmethanamines bearing a (hetero)aromatic substituent at the alfa-carbon, alkylamines afforded only imino-oximes. A possible reaction path is presented." .
