The addition reaction of lithium benzenethiolate to 2-buten-4-olide in the presence of aldehydes and ketones afforded α-substituted β-phenylthio-γ-butyrolactones (<B>4a</B>–<B>f</B>). The dehydrosulfenylation of <B>4a</B>–<B>d</B> proceeded smoothly to give 2-substituted 2-buten-4-olide by the reflux of α-substituted β-phenylsulfinyl-γ-butyrolactone, which was prepared by the oxidation of <B>4a</B>–<B>d</B>, in the presence of triethylamine.
