α-Oxoketenedithioacetals 1 are shown to undergo highly selective conjugate reduction with Zn/ZnCl2-TMEDA in refluxing ethanol under controlled reaction conditions to afford β-methylthiomethylene ketones 6, β-methylthioketones 7 and the completely desulphurized α-methylketones 8 in sequential manner.
