Propargyl alcohol was converted into 4-acetoxy-cis-crotonaldehyde diethyl acetal (III) via three steps, cis-Hydroxylation of III with potassium permanganate followed by acetylation yielded tri-O-acetyl-DL-erythrose diethyl acetal (IV). Hydrolysis of IV afforded syrupy DL-erythrose (VI) which could be converted into erythritol (VII) and its dibenzylidene derivative. An acid hydrolysis of III gave 4
