This alkaloid has been isolated from the roots of Thalictrum dasycarpum
Fisch. et al. It crystallizes as colourless rods from Et20 or needles from EtOH.
It has a specific rotation of[α]
25 D - 210° (c 0.21, CHCI3) and gives an ultraviolet spectrum in EtOH with a single absorption maximum at 289 nm. The
methyl ether forms needles from Et20-EtOH with m.p. 91-2°C. The structure
has been proved by total synthesis of the base.
