Abstract
2-Oxo-8, 10-dihydroxy-△1, 9;3, 4-hexahydronaphthy1-7-acetic acid lactone underwent rearrangement to 2, 4, 8- and 1, 4, 8-trihydroxytetrahydronaphthy1-7-acetic acid lactone by dilute sulfuric acid, and to 2, 4-diacetoxy-8-hydroxytetrahydronaphthy1-7-acetic acid lactone by acetic anhydride and sulfuric acid. It was concluded that when hydroquinone rearrangement was hindered a resorcinol rearrangement might take place instead of catechol rearrangement. A synthesis of 1, 4, 8-trihydroxytetrahydronaphthty1-7-acetic acid lactone was also described.
