An improved method of preparation of halopropargyl alcohol is described. Hydration of halopropargyl alcohol followed by hydrolysis gave dihydroxyacetone which was identified as its dibenzoate. 2-Butyne-1, 4-diol was converted into acetoxymethyl vinyl ketone. 1, 4- Diacetoxy-3-bromobutan-2-one obtained by the addition of acetyl hypobromite to the vinyl ketone was treated with silver acetate to yield tri-O-acetyl-DL-erythrulose. Hydrolysis of the ...
