1-Methoxy-9H-carbazole-3-carbaldehyde Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
This simple carbazole alkaloid is found in the stem bark of Mu"aya koenigii
Spreng. It is best purified by sublimation of the crude base when it yields colour_x0002_less crystals. The ultraviolet spectrum in ethanol has absorption maxima at 238,
247,274,289 and 335 mJJ.. The structure has been shown to be 3-formyl-lmethoxycarbazole by spectroscopic methods and synthesis. It yields an oxime,
m.p. l55-6°C; a picrate, m.p. 198-2000 C and the 2:4-dinitrophenylhydrazone,
m.p. > 300°C. The N-methyl derivative forms colourless needles from C6H6-
light petroleum, m.p. l48-9°C. When subjected to Wolff-Kishner reduction, the
alkaline phase yields l-hydroxy-3-methyl-carbazole.
