Participants

Reaction Steps

To diallyl L-glutamate p-toluene sulfonate (the TsOH salt of diallyl L-glutamate) (1.08 g, 2.7 mmol, NovaBiochem) and triphosgene (0.30 g, 1.03 mmol) in 20 mL toluene, stirred at −78° C., trietylamine (0.86 mL, 6.2 mmol) was added. After 30 min, the reaction mixture was allowed to reach room temperature and was used without further purification. A typical IR spectrum was obtained v=2253 cm−1 (NCO, v. intense).
