In the title compound, C(19)H(19)NO(13), one of the two fused furan-ose rings adopts an envelope conformation whereas the other displays a twisted conformation. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions between a methine H atom and the triacetoxy-phenyl ring of an adjacent mol-ecule, and by weak non-classical inter-molecular C-H⋯O hydrogen bonds.
在标题化合物C₁₉H₁₉NO₁₃中,两个稠合呋喃糖环中的一个呈信封构象,而另一个呈扭曲构象。晶体结构通过次甲基H原子与相邻分子的三乙酰氧基苯环之间的分子间C-H⋯π相互作用以及弱的非经典分子间C-H⋯O氢键得以稳定。
