Abstract

In the title compound, C(26)H(22)O(4), the pyranone ring adopts a twisted boat conformation, while the cyclohexane ring is close to an envelope conformation. The dihedral angle between the mean planes of the coumarin and naphthalene systems is 78.8(1) degree. The attached phenyl ring is in an equatorial position with respect to the cyclohexane ring.

摘要

在标题化合物C₂₆H₂₂O₄中，吡喃酮环呈扭曲船式构象，而环己烷环接近信封式构象。香豆素和萘体系平均平面之间的二面角为78.8(1)°。连接的苯环相对于环己烷环处于平伏位置。
