γ-Acyl- and related δ-lactones having no 6 substituents were synthesized in a sequence of reactions, 1,4-conjugate additions of sulfurstabilized acetate anions to α,β-unsaturated ketones, followed by trapping of the resultant ketone enolates with formaldehyde, mild lactonization, and desulfurization.
