Abstract The total assignment of the 13 C‐shifts of the complex Vinica rosea L. alkaloids vincaleucoblastine, leurosidine and leurosine and of a synthetic isomer of the latter is presented. The structure of leurosidine is corrected and a tentative structure for the acid‐catalyzed product of isomerization of leurosine is proposed.
