Revisions Based on 13C N.M.R. Analysis.—The revision of the structures of five C19 diterpenoid alkaloids on the basis of the 13C n.m.r. spectral data has been reported.8,9 Yunusov and co-workers,10 relying predominantly on mass-spectral data, had proposed structure (43) for acomonine (C2jH41N07), isolated from the roots of Aconitum monticola. Based partially on chemical correlations with acomonine, they later assigned structures to iliensine (44) (Cj NO,)11 and 14-dehydroiliensine (45),12 isolated from Delphinium biternatum. These were the first reported C19 diterpenoid alkaloids lacking an oxygen function at C-l.

Acomonine.—Soviet researchers have reported the isolation of a new lycoctonine-type alkaloid, acomonine (6), which has no oxygen functionality at C-1. This base, C25H41NO7, m.p. 208—210 °C, was isolated from the roots of Aconitum monticola, co-occurring with songorine (7) and norsongorine (8).
