Specific enolates of unsymmetrical ketones can be obtained by reduction of an alpha, beta-unsaturated ketone (enone) with lithium-(0) in liquefied ammonia. Alkylation of the derived enolate gives an alpha-alkyl derivative of the corresponding saturated ketone, which is not the same as that obtained by a base-mediated enolization/alkylation of the saturated ketone itself. Provide an explanation for the turnover in the regiochemical course of the alkylation reactions.
