A REINVESTIGATION OF THE STRUCTURES OF ACOMONINE, ILIENSINE, 14-DEHYDROILIENSINE, AND 14-BENZOYLILIENSINE

Pelletier, S. William,Mody, Naresh V.

, p. 207 - 210 (2007/10/02)

The novel structures assigned by Yunusov et al to the C19-diterpenoid alkaloids, acomonine (1), iliensine (2), 14-dehydroiliensine (3), and 14-benzoyliliensine (4) have been found to be in error.We have demonstrated that these alkaloids are identical with the well-known alkaloids, delsoline (5), delcosine (6), 14-dehydrodelcosine (7), and 14-benzoyldelcosine (8), respectively.
