Aminoketene dithioacetals add to α,β-unsaturatedketones to give 1,5-diketones after hydrolytic work-up. Upon treatment with acid or base, these diketones suffer intramolecular aldol reactions yielding cyclohex-2-en-1,4-dione monodithioacetals, interesting and useful synthetic equivalents of cyclohex-2-en-1,4-diones which readily undergo conjugate addition and cycloaddition reactions.
