Reaction of sporinaphthalenones with hydroxylamine: Part II. Structure of product in the reaction of 1'-substituted spironaphthalenone

Reaction of 1'-aryl substitured spironaphthalenones 1a-d with hydroxylamine hydrochloride in ethanol gave substituted cinnamic ester derivatives 4a-d. Similarly, reaction of spironaphthalenone 1a with different alcohols gave the corresponding esters 4i-m.

Reaction of spironaphthalenones with hydroxylamine: Part III. A novel mechanism for the formation of products and trapping of an intermediate

A mechanism involving the intermediacy of nitrene 5, formed from the oxime of spironaphthalenone 1 by acid catalysed dehydration, has been proposed to explain the formation of pyrrolotropones/pyrrolo esters from spironaphthalenones. The initially formed n
