Reactions of 2-aminotropone with heterocumulenes, N,N'-diphenylcarbodiimide, phenyl isothiocyanate, phenyl isocyanate, and carbon disulfide, in the presence of t-BuOK afforded 1-phenylcycloheptaimidazole-2(1H)-phenylimine, 1-phenylcyclohepataimidazole-2(1H)-thione, 1-phenylcycloheptaimidazol-2(1H)-one along with 2H-cycloheptaoxazol-2-one, and 2H-cycloheptathiazol-2-one along with 2H-cycloheptaoxazole-2-thione in good to moderate yields, respectively.

, p. 1675 - 1682 (2007/10/03)
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.
