    摘要: The present invention provides a process for preparing 3-amino-2-hydroxypropionic acid derivatives (1) which does not use dangerous reagents, is economically advantageous, and is suitable for an industrial production, which process comprises: treating N-protected-3-amino-2-hydroxypropionic acid derivatives (2) having a steric configuration at 2-position carbon reverse to that of derivatives (1) with a leaving group-introducing agent to convert into N-protected-3-aminopropionic acid derivatives (3), then treating the derivatives with a basic substance to convert into substituted-3-amino-2-hydroxypropionic acid derivatives (4) having an inverted steric configuration at 2-position carbon, and then converting the derivatives into 3-amino-2-hydroxypropionic acid derivatives (1).
