YieldReaction ConditionsOperation in experiment
59% In tetrahydrofuran; at 0 - 20℃; for 3.0h; Lac-OCA was prepared as described previously [9-11], however, triphosgene was used rather than diphosgene. Briefly, the lithium salt of L-lactic acid (0.5 mol) was suspended in anhydrous THF (350 mL) at 0 C. Next, a solution containing triphosgene (0.3 mol) in anhydrous THF (150 mL) was added dropwise at 0-5 C, and the reaction mixture was stirred at room temperature for 3 h. THF was removed under reduced pressure, and diethyl ether (1 L) was added to the residue. Lastly, the lithium salts were removed by filtration, and recrystallization from tert-butyl methyl ether afforded colorless crystals in 59% yield.
