Glycerol → 3-Trityloxypropane-1,2-diol

Participants

Reaction Steps

In 50 ml of pyridine was dissolved 4.6 g (50 mmol) of glycerol followed by addition of 13.9 g (50 mmol) of trityl chloride and the mixture was stirred at ambient temperature overnight. The reaction mixture was then concentrated under reduced pressure and the residue was diluted with water and extracted with ether. The organic layer was washed with water, dried over magnesium sulfate, and concentrated. The residue was purified by column chromatography (silica gel/chloroform-methanol) to provide 9.5 g (59%) of 1-O-tritylglycerol.
