Reaction Steps

0.3 ml of Jones reagent (J. Chem. Soc. 1953., 2555) is instilled in a solution of 150 mg of the above-produced aldehyde in 11 ml of acetone with stirring at -30° C. and stirred for one hour at -30° C. Then, 0.23 ml of isopropanol is added, stirred for 15 minutes, diluted with ether, filtered, washed neutral with brine, dried on magnesium sulfate and concentrated by evaporation in a vacuum. The residue is chromatographed on silica gel. With hexane/0-50% ethyl acetate, 52 mg of (5RS)-5-acetoxy-5-{3-[(1E,3E)-(5RS)-5-acetoxy1,3-tridecadienyl]-phenyl}-pentanoic acid is obtained as colorless oil.
