Abstract

Reaction of 1'-aryl substituted 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 unsymmetrical spironaphthalenones 1e-h with hydroxylamine hydrochloride in presence of ethanol gave the respective esters 4e-h. All the esters were characterised by their spectral data.
