Process for producing alpha-aminoketones |
| 摘要 |
An amino group of an alpha-amino acid ester is protected as an imine, and it is then reacted with a halomethyllithium to obtain an N-protected-alpha-aminohalomethylketone. Further, this N-protected-alpha-aminohalomethylketone is treated with an acid to obtain an alpha-aminohalomethylketone. This process is suited for industrial production, and can produce an alpha-aminohalomethylketone and its related compounds economically and efficiently.
