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