Abstract

The title compound, C16H24O10·0.11H2O, is a key intermediate in the synthesis of 2-deoxy-2-[18F]fluoro- d-glucose (18F-FDG), which is the most widely used molecular-imaging probe for positron emission tomography (PET). The crystal structure has two independent molecules ( A and B) in the asymmetric unit, with closely comparable geometries. The pyranose ring adopts a 4 C1 conformation [Cremer-Pople puckering parameters: Q = 0.553 (2) Å, θ = 16.2 (2)° and ϕ = 290.4 (8)° for molecule A, and Q = 0.529 (2) Å, θ =15.3 (3)° and ϕ = 268.2 (9)° for molecule B], and the dioxolane ring adopts an envelope conformation. The chiral centre in the dioxolane ring, introduced during the synthesis of the compound, has an R configuration, with the ethoxy group exo to the mannopyranose ring. The asymmetric unit also contains one water molecule with a refined site-occupancy factor of 0.222 (8), which bridges between molecules A and B via O-H...O hydrogen bonds. [ABSTRACT FROM AUTHOR]

44. The viscera histomorphologic changes of the rats following the decrease of serum testoserone.

Author

Yan Yi and Xie Min-Hao

Abstract

The article studies the histomorphologic changes in the kidneys, livers and hearts of rats after the decline of the serum testosterone due to exercise in China. This was evident in a group of rats that were forced to continue training beyond a five-week intermittent anaerobic swimming training with a load equal to 5% of their weight.

46. Isopropyl 4-nitro-benzoate.

Author

Zou P, Xie MH, Wu H, Liu YL, and Chen ZP

Abstract

In the mol-ecule of the title compound, C(10)H(11)NO(4), the nitro group is approximately coplanar with the benzene ring [dihedral angle = 4.57 (10)°], while the carboxyl-ate group is slightly twisted, making an angle of 12.16 (8)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonding and π-π stacking inter-actions [centroid-centroid distances = 3.670 (2) and 3.665 (2) Å] are observed.

47. 2-Chloro-ethyl 4-nitro-benzoate.

Author

Wu H, Xie MH, Zou P, Liu YL, and He YJ

Abstract

The title compound, C(9)H(8)ClNO(4), crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the carboxyl-ate group is nearly coplanar with the benzene ring, forming dihedral angles of 2.4 (1) and 4.9 (1)°. In the crystal, mol-ecules are linked through weak C-H⋯O and C-H⋯Cl hydrogen bonds. A short O⋯N contact of 2.7660 (19) Å occurs between the nitro groups of adjacent mol-ecules.
