title: (R)-3,4,5-Tride-oxy-5,6-didehydro-1,2-O-(2,2,2-trichloro-ethyl-idene)-α-d-gluco-furan-ose-6,3-carbolactone: a new derivative of α-chloralose.
abstract: 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.
