• Beschreibung

  One of the numerous alkaloids obtained from the Lycopodium species, this base occurs in L. sausaurus and gives colourless crystals from Me₂CO. It is laevorotatory having [α]²⁰_D - 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 Me₂CO, 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.).
