Beschreibung
The leaves of Pleiocarpa pycnantha (K. Schum) Stapf. var. tubicina (Stapf.)
Pichon contain this alkaloid which crystallizes as colourless prisms from either
aqueous Me2CO or Et2O-pentane. It has[α]
23D- 67° (c 0.61, CHCI3 ) and gives
an ultraviolet spectrum having absorption maxima at 207,244 and 298 Mu.
The N-formyl derivative yields long, transparent prisms, m.p. l48-9°C. The
above structure has been confirmed by the synthesis of the optically inactive
base.
