Synthesis and Crystal Structure of 1,3-Bis(5 and Its Conversion To a Macrocyclic Derivative

Abstract

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 1 H 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) angstrom, beta = 105.892(2) degrees, V = 1291.00(9) angstrom(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 in the synthesis of new, functional macrocyclic systems.
