Long Range Interaction

4,4′-Bis(dicyanomethylene)bicyclohexylidine and its dihydro derivative, 4,4′-bis(dicyanomethylene)bicyclohexyl were prepared from the condensation of malononitrile with the corresponding diketone. Bicyclohexylidene-4,4′-dione was synthesized from the monoketal of cyclohexanedione via the symmetric azosulfide.The uv spectra of the 4,4′-bis(dicyanomethylene)bicyclohexylidine and related model compounds indicate the presence of a long range interaction between the dicyanomethylene groups of the title compound.

The natural abundance 13C nuclear magnetic resonance spectra of a number of spirobenzylisoquinoline alkaloids and related model compounds have been recorded. The carbon resonances of the alkaloids were assigned by comparison with the spectra of other isoquinoline alkaloids and with those of the model compounds. It has been shown that 13C nmr spectroscopy may be used to differentiate between diastereomers in this series.
