(12α)-3,18-Dihydro-17-methyllycodin-1(2H)-one Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
One of the numerous alkaloids obtained from the Lycopodium species, this base occurs in L. sausaurus and gives colourless crystals from Me
2CO. It is laevorotatory having [α]
20D
- 71.8° (c 0.792, EtOH). The ultraviolet spectrum consists
of a single absorption maximum at 257 mJ.l.. The alkaloid may be characterized as
the methiodide which forms colourless needles from aqueous Me
2CO, m.p.
258°C. When heated with Pd-C in a stream of nitrogen at 290-300°C it yields
7-methylquinoline and 6-methyl-a-pyridone. From the above structure it will be
seen that the alkaloid is a stereoisomer of a-Obscurine (q.v.).
