The title compound, C 22 H22 O 5, crystallizes with two molecules in the asymmetric unit, one of which shows disorder of its ethyl acetate group over two sets of sites in a 0.880 (2):0.120 (2) ratio. The C C distances in the two molecules are almost the same [1.1939 (16) and 1.199 (2) A ̊ ], but the Csp3 C C angles differ somewhat [175.92 (12) and 172.53 (16)]. In the crystal, several weak C—HO interactions are seen.
