Abstract

In the title compound, C(24)H(25)O(7)P, the δ-valerolactonyl ring exists in a distorted screw-boat conformation with the diethoxy-phosphoryl substituent occupying an axial position. The latter adopts an almost syn-periplanar conformation around the P-C bond. The mol-ecules form centrosymmetric dimers connected by O-H⋯O hydrogen bonds.

摘要

在标题化合物C(24)H(25)O(7)P中，δ-戊内酯环以扭曲的船式构象存在，二乙氧基磷酰基取代基占据轴向位置。后者围绕P-C键采取几乎顺式-邻位平面构象。分子通过O-H⋯O氢键形成中心对称二聚体。
