1-Acyl-4-(2,6-dimethylphenyl)-1,2,4-triaza-1,3-dienes (7), generated in situ upon manganese dioxide oxidation of the corresponding N-acyl-N'-(2,6-dimethylphenylaminomethylene)hydrazines (6), give the bridged heterocyclic compounds (10) via 1,6-electrocyclisation followed by Diels-Alder dimerisation.The isonitrile (8) is also obtained as a minor fragmentation product.
