Participants

Reaction Steps

A solution of Jones Reagent (a 2.67M solution in sulphuric acid; 2.07 ml, 5.5 mmol) was added dropwise to a solution of 4-hydroxy-6-phenylhex-2-ynoic acid (750 mg, 3.7 mmol) in acetone (12 ml) at 0° and the reaction mixture was maintained at 0° for 70 minutes. The mixture was quenched with ethanol (2 ml) and extracted with ethyl ether. Evaporation of the dried (magnesium sulphate) extracts gave the title acid as a yellow oil which was used directly in the next step.
