  Chiroptical spectra and molecular geometry of bicyclic dithioimides

  摘要：

  Several chiral bicyclic dithioimides were prepared by thionation of the parent imides with Lawesson's reagent. Due to a flexibility of the dithioimide chromophore, their CD spectra show significant solvent dependence. A substantial deviation of the chromophore from planarity was confirmed by the MNDO calculations and crystallographic structures of 4, 5b, 6 and 7. The observed CE sign corresponding to the lowest energy n-pi* transition can be predicted, upon careful examination of the molecular geometry, by the antioctant rule with sector signs opposite to those known for ketones.

  Molecular geometry and circular dichroism spectra of bicyclo[2.2.1]heptane-2,3-dicarboxylic anhydrides and imides

  摘要：

  Several tricyclic anhydrides and imides derived from optically active bicyclo[2.2.1]heptane-2,3-dicarboxylic acids were synthesized, and their circular dichroism spectra are reported. On the basis of MNDO calculations it was estalished that despite rigidity of the norbornane system the five-membered rings of succinic anhydride and imide moieties are slightly twisted. The chromophores are flexible and can be more or less skewed depending on solvent polarity. The chromophore nonplanarity significantly influences magnitude and sign of the first Cotton effect associated with the lowest energy n-pi* electronic transition. The sign of the second n-pi* Cotton effect is governed by vicinal effect of substituents. The crystal structures of three N-(S)-1-phenylethylimides were solved to establish the configuration at C-2 of the imide moieties.

  suhstituted N-nitrosopyrrolidines were prepared and their chiroptical spectra studied. The circular dichroism of monocyclic compounds depends on substituents, solvents, and temperature changes. Some of these N-nitrosamines exhibit bisignate CD curves in the region of n-π * transition. On the contrary, conformationally restrictcd bi- and tricyclic compounds show monosignate Cotton effects, the magnitudes
