Crystal structure of 3-de­oxy-3-nitro­methyl-1,2;5,6-di-O-iso­propyl­idene-α-d-allo­furan­ose

The title compound, C(13)H(21)NO(7) {systematic name: (3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-dimethyl-6-(nitro­meth­yl)tetra­hydro­furo[2,3-d][1,3]dioxole}, consists of a substituted 2,2-di­methyl­tetra­hydro­furo[2,3-d][1,3]dioxolane skeleton. The furan­ose ring A adopts a (o)T (4) conformation. The fused dioxolane ring B and the substituent dioxolane ring C also have twisted conformations. There are no strong hydrogen bonds in the crystal structure: only weak C—H⋯O contacts are present, which link the mol­ecules to form a three-dimensional structure.
