  An Intramolecularly Hydrogen Bonded Dihydrotripyrrinone

  摘要：

  A yellow tripyrrole analog (1) of bilirubin has been synthesized, and its lone propionic acid group is found to engage in conformation determining, intramolecular hydrogen bonding in solution and in the crystal. Molecular modelling and X-ray crystallography reveal an abbreviated ridge-tile or L-shape conformation in which an essentially planar dipyninone is hydrogen bonded to the single opposing propionic acid group. In the (arbitrary) (P)-helicity ridge-tile, the torsion angles about C(10) are computed to be 55 degrees and 61 degrees by molecular dynamics and found to be 66 degrees and 53 degrees in the crystal. Such torsion angles lead to an interplanar dihedral angle (similar to 93 degrees) between the dipyninone and its adjoining pyrrole that is very close to the dihedral angle (similar to 98 degrees) found in intramolecularly hydrogen bonded bilirubin.
