Reaction Steps

21 ml of (R)-(−)-2,2-dimethyl-1,3-dioxolane-4-methanol, 29 grams of powdered potassium hydroxide and 32 ml of 1-bromooctane were stirred in 150 ml benzene and refluxed for 6 hours, while removing the water formed by azeotropic distillation. The volume of the solvent was gradually reduced to about 100 ml. The reaction mixture was then cooled to room temperature and 200 ml water was added. The reaction mixture was then extracted thrice with 150 ml diethyl ether, the combined organic phase was washed with 100 ml water, and the solvent was then removed under reduced pressure. The obtained residue was dissolved in 100 ml of a 90:10:5 (v/v) mixture of methanol:water:concentrated hydrochloric acid, and the resulting solution was refluxed for 2 hours, followed by cooling to room temperature and addition of 100 ml water. The product was extracted thrice with 150 ml chloroform, washed consecutively with 150 ml water, 150 ml of saturated aqueous solution of sodium bicarbonate, and again with 100 ml water. The solvent was dried over anhydrous Na2SO4, filtered, and removed under reduced pressure, yielding 34 grams of (S)-1-octyl-glycerol.
