Crystal structure of 3-deoxy-3-nitromethyl-1,2;5,6-di-O-isopropylidene-α-d-allofuranose
The title compound, C13H21NO7 {systematic name: (3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-dimethyl-6-(nitro-meth-yl)tetra-hydro-furo[2,3-d][1,3]dioxole}, consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring A adopts a (o)T 4 conformation. The fused dioxolane ring B and the substituent dioxolane ring C also have twisted confo...

The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetra-hedron, one Et...
متن کاملCrystal structure of 1,2,3,4-di-O-methylene-α-d-galactopyranose
The title compound, C8H12O6, was synthesized by de-acetyl-ation of 6-acetyl-1,2,3,4-di-O-methyl-ene-α-d-galactose with sodium methoxide. The central part of the mol-ecule consists of a six-membered C5O pyran-ose ring with a twist-boat conformation. Both fused dioxolane rings adopt an envelope conformation with C and O atoms as the flap. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds are present...
متن کاملCrystal structure of 1,2,3,5-di-O-methylene-α-d-xylofuranose
The title compound, C7H10O5, was synthesized by reaction of d-xylose with paraformaldehyde. In the crystal, the central part of the mol-ecule consists of a five-membered C4O ring with an envelope conformation, with the methine C atom adjacent to the O atom being the flap. The protected O atoms of both cyclic acetal groups are oriented so that the four chiral C atoms of the furan-ose part show a...

In the title mol-ecule, C(16)H(16)BrN(5)O(3)S, the 1,3,4-thia-diazole ring is situated under the benzene ring, forming a dihedral angle of 86.6 (2)°, and with an S⋯Cg (where Cg is the centroid of the benzene ring) distance of 3.312 (3) Å. The benzene and 1,3,4-thia-diazole rings form dihedral angles of 83.8 (3) and 57.7 (2)°, respectively, with the central pyrazole ring. In the absence of class...
