A FACILE SYNTHESIS OF β-OXOTHIOLCARBOXYLATES FROM α-OXOKETENEDITHIOACETALS^*

Abstract

α-Oxoketenedithioacetals and alkenoyl ketenedithioacetals underwent facile, boron trifluoride etherate assisted partial hydrolysis in dioxane to afford β-oxothiolcarboxylates and γ, δ-unsaturated β-oxothiolcarboxylates, respectively, in good yields.
