THE TITLE COMPOUND [SYSTEMATIC NAME: (R)-2-trichloro-methyl-3a,3b,7a,8a-tetra-hydro-5H-pyrano[2',3':4,5]furano[2,3-d][1,3]dioxol-5-one], C(9)H(7)Cl(3)O(5), a triyclic system that contains a central α-d-furan-ose ring cis-fused with a dioxolane ring as well as a δ-lactone ring, exhibits a twisted conformation. The CCl(3) group has an axial orientation. The furan-ose ring approximates an envelope conformation due to the α,β-unsaturated lactone functionality. The asymmetric unit contains two independent mol-ecules with almost identical geometries.
标题化合物[系统名称：(R)-2-三氯甲基-3a,3b,7a,8a-四氢-5H-吡喃并[2',3':4,5]呋喃并[2,3-d][1,3]二氧戊环-5-酮]，C(9)H(7)Cl(3)O(5)，是一个包含中心α-d-呋喃糖环与二氧戊环顺式稠合以及一个δ-内酯环的三环体系，呈现扭曲构象。CCl(3)基团具有轴向取向。由于α,β-不饱和内酯官能团，呋喃糖环近似信封式构象。不对称单元包含两个几何结构几乎相同的独立分子。
