Notes:
Thermolysis of 5,6-epimino-5,6-dihydro-β-ionone (1) and its N-methyl derivative (2) leads to their monocyclic isomers 6 and 10, respectively, presumably due to a direct [1,5]-H shift; on prolonged heating, these isomers are converted easily into pyrrole derivatives. In contrast, the thermoisomer 12 resulting from 5,6-(N-methoxycarbonyl)epimino-5,6-dihydro-β-ionone (3) by the same mechanism, does not undergo further ring transformation, but equilibrates with its more stable tautomer 13.
