Condelphine from Delphinium confusum and D. denudatum has been assigned19 structure (26) on the basis of chemical and spectral evidence. The configuration of the C(15)-methoxy-group was unassigned and the absolute configuration of the molecule was assumed by analogy with that of other diterpenoid alkaloids. [Pg.253]

The alkaloid condelphine (CCCLII) was first isolated in 1942 from Delphinium confusum Popov and was found to be an 0-acetate derivative of isotalatizidine (CCCLIII) (142). The latter alkaloid, along with its C-1 epimer talatizidine (CCCLIV), had been isolated 2 years earlier from Aconitum talassicum Popov, a rare species native to the mountainous... [Pg.99]

Structure and Absolute Configuration of Condelphine Hydroiodide.—Condel-phine, C25H39NO6, m.pt. 158—159 °C, has been isolated from Delphinium denu-datum and from D. confusum. This alkaloid was correlated with isotalatizidine (31) and talatizidine (32). On treatment with methyl iodide in a sealed tube at 80 °C, the hydroiodide derivative, rather than the methiodide, was obtained. X-Ray crystallographic structural investigations of this hydroiodide have shown the structure of condelphine to be (33), refined to R — 0.100, based on 3828 observed reflections.26... [Pg.225]

The two genera Aconitum and Delphinium, which belong to the family Ranunculaceae, produce several series of closely related monobasic alkaloids. In fact, the same alkaloid may be found in different species of the two genera thus, isotalatisidine and its acetyl ester condelphine occur in A. talassicum and in D. confusum, respectively, and esters of lycoctonine occur in A. lycoctonum and in several Delphinium species. On the other hand, closely similar plant species (e.g., A. septentrioncde and A. lycoctonum, and a series of East Asian Aconitum species) may be differentiated by their content of related but different bases. [Pg.275]
