The generation of α,β:γ,5-unsaturated azomethine ylides 8 is described, starting from TV-substituted α-amino acids 7 and aldehydes 6,12. These azomethine ylides undergo a 1,7-electrocyclisation, followed by a [l,5]-hydrogen shift, to give the dihydrobenza
1,7-Electrocyclisation of non-stabilised azomethine ylides

Non-stabilised α,β,γ,δ-unsaturated azomethine ylides 3 were generated by the decarboxylation method from 3,3-diarylpropenals 1 and secondary amino acids 2. 1,7-Electrocyclisation of these azomethine ylides, followed by a 1,5-hydrogen shift, gives 2,3-dihydro-1H-2-benzazepines 4.
