Catalyzed N-alkylation of N,O-bistrimethylsilyl pyroglutamic acid with trimethylsilyl benzhydryl ethers yields trimethylsilyl N-benzhydrylpyroglutamates. Hydrolysis of these compounds or saponification of the methyl esters gives the corresponding acids.
用三甲基甲硅烷基苯甲酰基醚催化N ,O-双三甲基甲硅烷基焦谷氨酸的N-烷基化,得到三甲基甲硅烷基N-苯甲酰基焦谷氨酸酯。这些化合物的水解或甲酯的皂化得到相应的酸。
