Pyrrolo[2,1-b]quinazolin-9(1H)-one, 2,3-dihydro-5-methoxy-3-[4-(methylamino)phenyl]- (9CI) Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Anisotes sessiliflorus C. B. Cl yields this alkaloid which forms colourless crystals from MeOH. The ultraviolet spectrum in neutral solution (EtOH) has absorption maxima at 212, 239, 286, 315 and 327 mJ.1. In acid solution (EtOH-HCl), the absorption maxima occur at exactly the same wavelengths. The earlier structure in which the benzene ring was linked through nitrogen has now been altered to that given above
