Palladium-catalyzed N-allylation of unprotected amino acids with 1,1-dimethylallyl alcohol were carried out. The reaction in the presence of Pd(OAc)(2) (5 mol%), sodium diphenylphosphinobenzene-3-sulfonate (TPPMS, 10 mol%), and AcONa (2 equiv) in water at 120 °C for 16 h in a sealed tube gave only mono-N-allylated amino acids in good yield.
钯催化的未保护氨基酸与 1,1-二甲基烯丙醇的 N-烯丙基化反应在 Pd(OAc)(2)(5mol%)、二苯膦基苯并噻唑-3-磺酸( TPPMS)(10mol%)和 AcONa(2当量)的存在下，在水相中于 120°C 密封管中反应 16 小时，仅得到单 N-烯丙基化的氨基酸，产率良好。
