• 説明

  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.
