Reactions of troponimines with carbon disulfide, phenyl isocyanate, tosyl isocyanate, or diphenylketene afforded dihydroazazulanone and azazulanone derivatives through -type cycloadducts.Reaction with dimethyl acetylenedicarboxylate gave a dihydroazazulene derivative and a quinoline derivative.

Tropone benzoyl- and tosylhydrazones underwent the cycloaddition reaction with isocyanates to afford the cycloheptaimidazolin-2-one derivatives.This means that these hydrazones behaved as 8-amino-8-azaheptafulvenes.Also, the tropone hydrazones re
