A 1,2-prototropy route and an iminium ion route to vinyl azomethine ylides are described.In both cases the vinyl azomethine ylides undergo 1,5-electrocyclisation to dihydropyrroles.In the former case the 1,5-electrocyclisation is solvent sensitive and completes with a prototropic process giving the imine of an α,β-unsaturated α-amino ester.The mechanism and solvent sensivity are discussed.In the latter case the dihydropyrrole reacts further with aldehydes via an aldol type condensation.
