The title compound tianagliflozin triacetate 1 was synthesized and its crystal structure was determined by single-crystal X-ray diffraction.The crystal belongs to monoclinic system(C27H31ClO8,Mr = 518.97),space group P21 with a = 5.3913(11),b = 16.137(2),c = 15.411(3) ,β = 94.15(3)°,V = 1337.3(5) 3,Z = 2,Dc = 1.289 g/cm3,F(000) = 548,μ = 0.190 mm-1,the final R = 0.0374 and wR = 0.0809 for 3981 observed reflections(I 2σ(I)).The structure of 1,triacetate of a highly potent SGLT2 inhibitor tianagliflozin,was unambiguously determined by single-crystal X-ray diffraction,which helped to confirm the desired β configuration at the anomeric center and the position where the deoxylation occurred.The two benzene rings in the lattice are basically orthogonal to each other.There are four intermolecular hydrogen bonds in the crystal,which helps to further stabilize the crystal. 相似文献

The title complex, C20H17N4Pd2Cl3·0.5CH3OH, crystallizes in the triclinic system, space group P1 with a = 9.927(6), b = 11.079(6), c = 11.233(6) ?, α = 73.970(12), β = 85.738(16), γ = 83.300(12)o, V = 1178.1(11)?3, Mr = 648.55, Z = 2, Dc = 1.520 g/cm3, μ = 1.884 mm-1, F(000) = 634, the final R = 0.0460 and wR = 0.1280. This title compound was investigated for the catalytic behavior towards norbornene(NB) vinyl addition polymerization. And the complex exhibits good catalytic activity to catalyze norbornene polymerization using MAO as a cocatalyst. 相似文献

A new mixed-valence heterometal cluster Mo8VW2VIO26(C5H5N)8·2H2O has been synthesized under solvothermal conditions and characterized by X-ray single-crystal diffraction, IR, UV-vis and XPS spectroscopy. The title compound crystallizes in the triclinic system, space group P1 with a = 11.708(3), b = 12.018(4), c = 13.316(4) , a = 112.184(4), β = 97.844(4), r = 110.043(3)o, V = 1551.9(8) 3 and Z = 1 at 293(2) K. The final full-matrix least-squares refinement converged to R = 0.0414 for 4460 observed unique reflections with I 2σ(I) and w R = 0.1290 for all data(5352) and S = 1.015. In addition, its thermal stability and fluorescent property have also been investigated. 相似文献

We describe here a rapid process for the preparation of new 9-chloromethyl-12-aryl-10,12-dihydrobenzo[5,6]chromeno[2,3-d]pyrimidin-11-ones 5a-d and 10-chloromethyl-7-aryl-7,9-dihydrobenzo[7,8]chromeno[2,3-d]pyrimidin-8-ones 6a-d by two different methods utilizing microwave irradiation. This methodology provides better yields(72%–80%) and high purity of the title compounds. 相似文献

The title compound was synthesized by the reaction of 4-tert-butyl-5-(4-chlorobenzyl)-2-aminothiazole with 2,6-difluorobenzoic acid. The crystal structure of the title compound, C21H19ClF2N2OS, was determined by single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group Pbca with a = 12.6479(13), b = 13.1204(13), c = 14.1341(15), Z = 4, V = 2011.5(4)3, Mr = 420.89, Dc = 1.390 g/cm3, S = 1.023, μ = 0.326 mm-1, F(000) = 872, the final R = 0.0365 and wR = 0.0880 for 6101 observed reflections(I 2σ(I)), and R = 0.0507, wR = 0.0978 for 7779 independent reflections. X-ray crystal structure displays that the hydrogen bonding interactions observed link the molecules to form a dimeric unit. The preliminary biological test of the title compound shows good antitumor activity, with IC50 of 0.046 μmol/mL against the Hela cell line. 相似文献
