Procedure

To a solution of (6Z,9Z)-18-(3-(allyloxy)-2-((9Z,12Z)-octadeca-9,12-dienyloxy)propoxy)octadeca-6,9-diene (9.1 g, 14.3 mmol) in ethanol (100 ml) was added trifluoroacetic acid (15.0 mL) and tetrakis(triphenylphosphine)palladium(0) (1.65 g, 1.43 mmol). The solution was refluxed for 16 hours, cooled to room temperature and concentrated in vacuo to dryness. The residue was purified by column chromatography on silica gel 60 (eluted with a gradient of 100% hexanes to 1:1 hexanes/DCM to 100% DCM) to afford 2,3-bis((9Z,12Z)-octadeca-9,12-dienyloxy)propan-1-ol as a colorless oil (6.1 g, 54%).
