Preparation of 2-nitro-2-cyclohexenone acetal starting from 2-nitrocyclohexanone acetal has been reported for the first time. This compound as well as 3-nitro-2-cyclohexenone acetal , whose synthesis has been reported by us earlier, react with a variety of nucleophiles to form highly functionalised intermediates. One of them viz. is converted into a bicyclic α- methylenen-γ-lactone using radical chemistry

Photolysis of 2-dialkylamino-2-cyclohexenones leads to α-ketoazetidines. The reactivity of 3-methyl-2-dialkylamino-2-cyclohexenones and the effect of the nature of the dialkylamino groups on the photocyclization are discussed. Photolysis of the corresponding ammonium salts in hydroxylic solvents led only to adduct formation.
