Abstract
Optically active 2-aralkyl-3-sulfonyloxy-1-propanol and 2-aralkyl-3-sulfonyloxypropionic acid are provided by using an optically active 2-aralkyl-3-acyloxy-1-propanol as a starting material. Furthermore, an optically active 2-aralkyl-3-thiopropionic acid, which is an important intermediate for synthesis of enkephalinase inhibitors, is provided. According to the present invention, industrially useful optically active sulfonic acid ester derivatives can be provided.
