A few representatives of the title ring system have been synthesised through a reaction sequence involving an intramolecular aza-Wittig cyclocondensation of appropriately ortho-substituted N-Aryl-C-(triphenylphosphinimido)hydrazones.The cyclisation yields spread over a wide range, being markedly dependent on the substituents.
