Participants

Reaction Steps

9.07 grams of 1-(cis-9-hexadecenyl)-glycerol was dissolved in a mixture of dry THF (160 ml) and dry acetonitrile (40 ml). 10.52 grams triphenylchloromethane and 10 ml triethylamine were added, and the reaction mixture was refluxed for 15 hours. The reaction mixture was cooled to room temperature, poured on ice (100 grams), transferred to a separatory funnel, and extracted thrice with 100 ml chloroform. The organic phase was washed consecutively with 100 ml water, 100 ml dilute (1.0%) sulfuric acid, 100 ml water, 100 ml saturated aqueous sodium bicarbonate, and again with 100 ml water. The organic phase was dried over anhydrous sodium sulfate and the solvent was removed under reduced pressure. The obtained residue was dissolved in hot hexane (100 ml) and the resulting solution was cooled at 4° C. for 36 hours. Filtration of precipitated by-products and removal of solvent under reduced pressure yielded 14.57 grams of crude product. The crude product was purified by chromatography over silica gel (200 grams). 9.81 grams of pure 1-(cis-9-hexadecenyl)-3-trityl-sn-glycerol was eluted with chloroform. The yield was 61.1%.
