In the presence of a small amount of catalyst (mainly triflic acid), methyl N-(trimethylsilyl)pyroglutamate quickly reacts with benzhydryl chlorides or preferentially with trimethylsilyl benzhydryl ethers to give methyl N-(benzhydryl)pyroglutamates in nearly quantitative isolated yields.
在少量催化剂(主要是
三氟甲磺酸)的存在下,N-(三甲基
硅基)焦谷
氨酸甲酯会迅速与
苯甲酰氯或优先与三甲基
硅基苯甲酰醚发生反应,生成 N-(苯甲酰)焦谷
氨酸甲酯,分离产率接近定量。
