Extraction of Fritillaria camtschatcensis, a known source of solanidine, has yielded tomatidenol (34), solasodine (16a), and a new alkaloid hapepunine, C2sH47N02. Hapepunine was assigned the N-methyl 22,26-epiminocholestane structure (35 a) on the basis of spectroscopic studies similar to those described above for teinemine. This structure proposal was proved by the partial synthesis of hapepunine from tomatidenol (34) via the desmethyl derivative (35b). Hapepunine (35 a) is the first natural 16j8-hydroxy-22,26-epiminochoIestane derivative. ... [Pg.249]
