Mechanism of the reduction of the alkaloids ofHaplophyllum at a dropping mercury electrode

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

1. The furanoquinoline alkaloids skimmianine, haploperine, and γ-fagarine are reduced at a dropping mercury electrode in 0.1 N (C2H5)4NI and (C2H5)4NOH in 80% ethanol forming tetrahydro or hexahydro derivatives according to the potential of the electrode.

2. Carbostyryl and N-methylcarbostyryl are reduced under the same conditions to the corresponding dihydro derivatives.

3. The proposed mechanism for the electrode processes is confirmed by a comparison of the UV and IR spectra of the substances before and after their electrolysis at a controlled potential with the spectra of synthetic compounds.
