(2-甲氧基苯基)-氨基甲酸-1,1-二甲基乙酯 | tert-butyl 2-methoxyphenylcarbamate | 154150-18-2 | C12H17NO3 | 223.272 |
We describe a mild and efficient method for the chemoselective N-benzyloxycarbonylation of amines by treatment of amines and aminoesters with benzyloxycarbonyl chloride (Cbz-Cl) in the presence of TBAB under solvent-free conditions in excellent yields. The method is general for the preparation of a wide variety of N-Cbz derivatives of aliphatic, aromatic amines, and aminoesters.
