Description
The empirical formula for this alkaloid should read C21H24N203 and the structure
is that given above. This alkaloid has been fully described by Malikov and his
colleagues. It forms colourless crystals with m.p. 222-3°C from MeOH and has
the following specific rotations: [α]
D- 57.3° (c 2.01, MeOH) and [α]
D - 83.5°
(c 0.3, pyridine). Among the crystalline salts and derivatives that have been
prepared are the hydrochloride, m.p. 265-8°C; hydrobromide, m.p. 285-6°C;
hydriodide, m.p. 255-8°C and the methiodide, m.p. 258-260°C.
