The title compound (Z)-ethyl-4-(4-methoxy)benzylidene-2-(3,5-dimethoxyphenyl)- tetrahydrofuran-3,3-dicarboxylate has been synthesized, and its crystal structure was characterized by X-ray single-crystal diffraction. The crystal belongs to triclinic, space group P1, with a = 8.140(3), b = 11.966(4), c = 13.771(5)Aα= 67.366(4), β= 85.165(5), γ= 75.806(4)°, V = 1200.1(7) A3, Z = 2, C26H3008, Mr = 470.50, Dc = 1.302 g/cm^3, F(000) = 500,λ(MoKa) = 0.71073 A, μ= 0.096 mm^-1, R = 0.0659 and wR = 0.1841 for 3080 observed reflections (I 〉 2σ(I)). As a key intermediate of HIV-1 integrase inhibitor, the synthesis and structure confirmation of the title compound are important for further studies. 展开更多

A facile procedure for the synthesis of 3-(2′-amino-3′-cyano-4′-arylpyrid-6′-yl) coumarins are being reported starting from 3- acetylcoumarin, aromatic aldehydes and malononitrile. The reactions were carried out on microwave irradiation in good yield with short time and easy work-up. The structures of all the compounds have been confirmed on the basis of their analytical, IR, ^1H NMR, and mass spectral data. 展开更多
