摘要:
A process which comprises converting a α-amino acid ester into the corresponding imine to thereby protect the amino group of the ester, reacting the imine with a halomethyllithium to form an N-protected α-amino halomethyl ketone, and treating this N-protected α-amino halomethyl ketone with an acid to obtain a α-amino halomethyl ketone. This process is suitable for industrial production and permits economical and efficient production of α-amino halomethyl ketones and compounds related thereto.
摘要:
An amino group of an α-amino acid ester is protected as an imine, and it is then reacted with a halomethyllithium to obtain an N-protected-α-aminohalomethylketone. Further, this N-protected-α-aminohalomethylketone is treated with an acid to obtain an α-aminohalomethylketone. This process is suited for industrial production, and can produce an α-aminohalomethylketone and its related compounds economically and efficiently.
