Spironaphthalenones 1b-g on reaction with hydroxylamine hydrochloride gave the expected pyrrolotropones 2b-g. Furanotropone 6, postulated as an intermediate in the formation of pyrrolotropones, remained unchanged on reaction with hydroxylamine hydrochloride in ethanol. Reaction of unsymmetrical spironaphthalenones 1h-o with NH2-OH.HCl gave the rearranged pyrrolotropones 2h-o.
