Abstract
In the title compound, C(27)H(30)O(8), the cyclo-hexane ring is in a chair conformation, while the five-membered ring adopts an envelope conformation. The 1,3-dioxane ring is oriented with respect to the benzene rings at dihedral angles of 53.38 (3) and 55.31 (3)°, while the dihedral angle between the benzene rings is 71.56 (3)°. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains.
摘要
在标题化合物C₂₇H₃₀O₈中，环己烷环呈椅式构象，而五元环呈信封式构象。1,3 - 二氧六环环相对于苯环的二面角为53.38 (3)°和55.31 (3)°，而苯环之间的二面角为71.56 (3)°。在晶体结构中，分子间的C—H⋯O相互作用将分子连接成链。
