Conclusions

  1. 1.

    The IR and NMR spectra of four series of compounds were taken, which were synthesized from lupinine and N-(β-hydroxyethyl)anabasine.

     
  2. 2.

    The trans-configuration of lupinine, with an axial OR group, does not change when alkyl or aryl radicals are introduced into the molecule.

     
  3. 3.

    For N-(β-hydroxyethyl)anabasine derivatives the isomer with an equatorial exterior substituent, and an axial direction of the unshared electron pair on the nitrogen atom, predominates.

     
  4. 4.

    Preferred conformations were proposed for lupinine and N-(β-hydroxyethyl)anabasine derivatives.
