Beschreibung

One of the numerous alkaloids which have been isolated from Vinca rosea L. (Syn. Catharanthus roseus G. Don.), this base yields colourless crystals from MeOH and is strongly laevorotatory with [α]_D - 528° (CHCl3) or [α]²⁷_D - 432° (CHCI3). The ultraviolet spectrum of the alkaloid in EtOH shows three absorption maxima at 226, 297 and 327 ffi/.l. The suggested structure contains one methoxycarbonyl group, an imino group, a bridge ethyl group and an epoxy ring. The second nitrogen atom is tertiary.
