The title compound 9-amino-7-(2-chlorophenyl)-6H-benzo[c]thiochromene-8,8,10(7H)-tricarbonitrile DMF solvate(C25H20ClN5OS,Mr = 473.97) was synthesized and crystallized.The crystal belongs to triclinic,space group P1 with a = 7.6393(2),b = 10.5212(3),c = 15.0573(4) ,α = 86.797(1),β = 79.445(1),γ = 75.379(1)°,Z = 2,V = 1151.16(5) 3,Dc = 1.367 g.cm-3,μ(MoKα) = 0.285 mm-1,F(000) = 492,R = 0.0389 and wR = 0.1005 for 3455 observed reflections(I > 2σ(I)).X-ray analysis reveals that the new six-numbered ring(C(1)-C(6)) forms a skew boat conformation.The molecule links a molecule of DMF via the N(1)-H(1A)...O(1) hydrogen bond,while another hydrogen bond C(23)-H(23A)...N(2) links adjacent molecules,forming dimmers along the a axis. 相似文献

The Darzens condensation reaction of aromatic aldehydes with phenacyl chloride proceeded very efficiently in a water suspension medium in the presence of triethylbenzylammonium chloride and only trans-2,3-epoxy-1,3-diaryl-1-propanones were formed which can be isolated simply by filtration.The structures of these compounds were confirmed by elemental analysis,IR and ^1H NMR spectra.Therir configurations are in agreement with that of the same compounds reported in the literature.Compared to the classical Darzens condensation,this new method has the advantages of good yields,high stereoselectivity,low running cost inexpensive and environmentally benign procedure. 相似文献
