Abstract

Abstract The magnesium 3, 3-dimethylcyclohex-1-enolate 1i, formed in the copper catalyzed addition of methylmagnesium iodide to 3-methylcyclohex-2-enone, has been subjected to regiospecific electrophilic reactions such as acylation, alkylation, and aldol condensation in order to find a new access to the damascones, ionones and carotenoids. By way of illustration a new synthesis of γ-damascone is described.
