Abstract

In the title compound, C14H14O4, the dihedral angle between the hydro-furan and benzene rings is 88.41 (15)°. The hydro-pyran ring adopts an envelope conformation, with the O-bound methyl-ene C atom as the flap. In the crystal, weak aromatic π-π stacking is observed [centroid-centroid separation = 3.848 (2) Å].

摘要

在标题化合物C₁₄H₁₄O₄中，氢呋喃环与苯环之间的二面角为88.41 (15)°。氢吡喃环呈信封构象，以与氧相连的亚甲基C原子作为翻盖。在晶体中，观察到弱的芳香π-π堆积作用[质心-质心间距 = 3.848 (2) Å]。
