PROCESS FOR PREPARING beta -AMINO- alpha -HYDROXY ACID DERIVATIVES
摘要
<p>A process for preparing beta -amino- alpha -hydroxy acid derivatives in an efficient and commercially useable manner. The process is characterized by hydrolyzing an alpha -amino- alpha ', alpha '-dihaloketone derivative represented by general formula (1) in the presence of a base, optionally followed by the protection of the amino group, to prepare a beta -amino- alpha -hydroxy acid derivative represented by general formula (2).</p>
