Synthesis And Crystal Structure Of 1,3-Bis(5-Formylpyrrol-2-Yl)Benzene And Its Conversion To A Macrocyclic Derivative, M. Kasim Şener, Davi̇d Sanches Garcia, Mehmet Akkurt, Sema Öztürk Yildirim, Hoong-Kun Fun, Jonathan L. Sessler
Turkish Journal of Chemistry
This report details the synthesis and characterization of a new diformyl pyrrole derivative 2 and its macrocyclic derivative 3. The new compounds were characterized by FT-IR, ^{13}C NMR, and ^1H NMR spectroscopies and via mass spectrometric analysis. The structure of 2 in the solid state was determined using X-ray diffraction methods (monoclinic, P2_1/c, a = 17.3760(7), b = 4.9719(2), c = 15.5374(5) Å, \beta = 105.892(2) °, V = 1291.00(9) Å^3, and Z = 4). The molecular structure is stabilized by N-H...O and C-H...O intermolecular hydrogen bonds. The present bisformylpyrrole derivative 2 provides a new precursor that may be useful …

Turkish Journal of Chemistry
Acetal of warfarin acid has been synthesized via a hemi acetal intermediate and structurally characterized by X-ray diffraction. The crystal structure shows that the title compound was formed by the hydrolysis of warfarin acid in methanol at pH 3, with space group P2_1/n and unit cell parameters a = 5.859 (17), b =16.745 (5), c = 16.402 (5) Å, \alpha = 90.00; \beta = 94.853 (4), and \gamma = 90.00°.
