Crystal structure of 1,2,3,5-di-O-methyl-ene-?-d-xylo-furan-ose.

ABSTRACT: 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 an R configuration. C-H?O hydrogen bonds are present between adjacent mol-ecules, generating a three-dimensional network.

Project description: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 conformations. There are no strong hydrogen bonds in the crystal structure: only weak C-H⋯O contacts are present, which link the mol-ecules to form a three-dimensional structure.

Crystal structure of 6-de-oxy-α-l-psico-furan-ose.

Project description:The title compound, C6H12O5, was crystallized from an aqueous solution of 6-de-oxy-l-psicose (6-de-oxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetra-hydroxy-hexan-2-one), and the mol-ecule was confirmed as α-furan-ose with a (3) T 4 (or E 4) conformation, which is a predominant tautomer in solution. This five-membered furan-ose ring structure is the second example in the field of the 6-de-oxy-ketohexose family. The cell volume of the title compound [742.67 (7) Å(3), Z = 4 at room temperature] is only 1.4% smaller than that of β-d-psico-pyran-ose, C6H12O6 (753.056 Å(3), Z = 4 at room temperature).

1,2:5,6-Di-O-iso-propyl-idene-3-C-methyl-?-d-allo-furan-ose.

Project description:The title carbohydrate, C13H22O6, is a derivative of d-glycose, in which the furan-osidic and iso-propyl-idene rings are in twisted conformations. The mean plane of the furan-osidic ring makes a dihedral angle of 70.32?(18)° with the mean plane of the fused iso-propyl-idene ring. The methyl groups in the other iso-propyl-idene ring are disordered over two sets of sites, with an occupancy ratio of 0.74?(6):0.26?(6). In the crystal, mol-ecules are linked by O-H?O hydrogen bonds into chains with graph-set notation C(5) along [100]. Weak C-H?O interactions also occur.

Project description:The title compound, C21H29NO7 (1) [systematic name: benzyl ({(3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-di-methyl-tetrahydro-furo[2,3-d][1,3]dioxol-6-yl}meth-yl)carbamate], consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring adopts an envelope conformation close to C 3-exo, where the C atom substituted by the benzyl carbamate group is the flap. The fused dioxolane ring also adopts an envelope conformation, as does the terminal dioxolane ring, with in each case an O atom as the flap. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming chains propagating along the b-axis direction.

Crystal structure of N'-[4-(di-methyl-amino)-benzyl-idene]furan-2-carbohydrazide monohydrate.

Project description:The condensation of 2-furoic hydrazide and 4-dimethyl amino-benzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by inter-molecular O(water)-H?O,N(carbohydrazide) and N-H?O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Additional C-H?O inter-actions link the mol-ecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47?(6)°. The carbohydrazide moiety, i.e., the C=N-N-C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75?(9)° between their mean planes.

Crystal structure of N'-(2,6-di-methyl-phen-yl)benzene-carboximidamide tetra-hydro-furan monosolvate.

Project description:The asymmetric unit of the title compound, C15H16N2·C4H8O, contains two amidine mol-ecules (A and B) with slightly different conformations and two tetra-hydro-furan (THF) solvent mol-ecules. In the amidine mol-ecules, the di-methyl-phenyl ring and the NH2 group lie to the same side of the N=C bond and the dihedral angles between the aromatic rings are 54.25 (7) (mol-ecule A) and 58.88 (6) ° (mol-ecule B). In the crystal, N-H⋯N hydrogen bonds link the amidine mol-ecules into [100] C(4) chains of alternating A and B mol-ecules. Both amidine mol-ecules form an N-H⋯O hydrogen bond to an adjacent THF solvent mol-ecule.

Crystal structure of the di-Mannich base 4,4'-di-chloro-3,3',5,5'-tetra-methyl-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

Project description:The title compound, C21H26Cl2N2O2, was prepared in a solvent-free microwave-assisted synthesis, and crystallizes in the ortho-rhom-bic space group Pna21. The imidazolidine ring adopts an envelope conformation and its mean plane is almost perpendicular to the two pendant aromatic rings [dihedral angles = 84.61 (9) and 86.54 (9)°]. The mol-ecular structure shows the presence of two intra-molecular O-H⋯N hydrogen bonds between the phenolic hy-droxy groups and imidazolidine N atoms. The two 3-chloro-6-hy-droxy-2,4-di-methyl-benzyl groups are located in a cis orientation with respect to the imidazolidine fragment. As a result, the lone pairs of electrons on the N atoms are presumed to be disposed in a syn conformation. This is therefore the first example of an exception to the 'rabbit-ears' effect in such 2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol derivatives.
