摘要

Aminoketene dithioacetals add to α, β-unsaturated ketones 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.
