Synthesis of novel 2,5-substituted 3-bis(methylthio)methylenetetrahydrofurans 4 by oxymercuration-reduction of α- bis(methylthio) methylene-γ,δ-unsaturated alcohols 2 is reported. The carbinols 2 are obtained from the corresponding allyl-(or 2-methyl-2-propenyl) acylketene dithioacetals 1 by sodium borohydride reduction or by treatment with methylmagnesium iodide.
