Delstaphidine (7) and neolinine (8), two new C19-diterpenoid alkaloids, and α-oxodelphinine (9) have been isolated from the seeds of Delphinium staphisagria.The structures of these alkaloids were determined on the basis of spectral data, correlation with alkaloids of established structures, preparation of certain derivatives and by synthesis. α-Oxodelphinine has not been isolated from a natural source previously.N-Deethyldelphisine (10) and N-deethyldelstaphidine (11), two new synthetic diterpenoid alkaloids, have been prepared by KMnO4 oxidation of delphisine.Oxidative cyclization of delphisine with alkaline potassium ferricyanide ga ve delstaphinine (6).
