| | stemmadenine Usage And Synthesis |
| Description | First isolated from various species of Stemmadenia, this alkaloid has subsequently
been found in DipZorrhynchus rondyZocarpon subsp. mossambiensis Benth. and
MeZodinus australis. The following specific rotations have been reported; [α]19D +
310° (c 0.527, pyridine), [α]20D~O + 329° (pyridine) and [α]25D~S + 324° (pyridine).
The alkaloid gives an ultraviolet spectrum exhibiting absorption maxima at 227,
284 and 292 m/J. with shoulders at 275 and 305 m/J.. One nitrogen atom is
tertiary, the other being part of the indole ring. The solution in concentrated
HN03 is a bright yellow. | | References | Watts, Collera, Sandoval., Tetrahedron, 2, 173 (1958)
