참여 물질

반응 단계

100 mmol of the glycerol derivative obtained in (b) in 10 ml of pyridine were reacted at room temperature overnight with 101 mmol of trityl chloride. The pyridine was removed under reduced pressure and the residue was taken up in 100 ml of ether. The solution was filtered, the ether was removed and the residue was treated with 10 ml of pyridine, 1 ml of water and 1 g of potassium bicarbonate and stirred at room temperature for 1 hour. The solvent was removed under reduced pressure and moisture residues were removed with toluene. The residue was taken up in toluene and chromatographed on silica gel with ether/pyridine (99:1). There was obtained (RS)-1-O-[3RS,7R,11R)-3,7,11,15-tetramethylhexadecyl]-3-O-tritylglycerol as an oil.
