Reaction Conditions

Reaction Steps

20 Parts of 9-oxodec-4-yn-1-ol of Example 4 is dissolved in 200 parts by volume of acetone and cooled to 0° C. The cold solution is stirred and treated dropwise with 90 parts by volume of 2.67 molar Jones reagent (chromic acid in sulfuric acid and water). The acetone solution is decanted from the solid chromium salts, which are then rinsed with fresh acetone. The acetone solutions are combined and poured into a mixture of ether and water. The ether layer is separated from the water, washed once with water, and then extracted three times with 5% potassium carbonate solution. The alkaline extracts are combined, acidified with concentrated hydrochloric acid and extracted twice with ether and once with ethyl acetate. The extracts are combined, dried over sodium sulfate, and stripped of solvent to give the pure product, 9-oxodec-4-ynoic acid.
