Six scalemic mixtures of 6-monosubstituted dihydrobenzophenanthridine alkaloids from Chelidonium majus and optically active structures of enantiomers

Six previously undescribed 6-monosubstituted dihydrobenzophenanthridine alkaloids were identified from C. majus, all characterizec as scalemic mixtures of enantiomers. Resolution and identification of absolute configurations were achieved.209
