(12α)-3,18-ジヒドロ-17-メチルリコジン-1(2H)-オン 化学特性,用途語,生産方法
説明
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.).
