Structural studies of benzophenanthridine alkaloid free bases by NMR spectroscopy

Original language description

The free bases of eight quaternary benzo[c]phenanthridine alkaloids were investigated by 1H and 13C NMR spectroscopy. The pseudobases (the 6-hydroxy-5,6-dihydro derivatives) were found to be the only products of the alkalization in DMSO-d6 solution. In less polar solvents the formation of the bimolecular aminoacetal structure is preferred. In biological systems, free bases of the alkaloids are assumed to adopt the pseudobase structure.
