description The title compound [systematic name: (R)-2-trichloro­methyl-3a,3b,7a,8a-tetra­hydro-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-furan­ose 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 furan­ose ring approximates an envelope conformation due to the α,β-unsaturated lactone functionality. The asymmetric unit contains two independent mol­ecules with almost identical geometries.
