Dehydrothalmelatine

Although earlier described from 3-year-old Thalictrum minus extracts as a probable artifact of air oxidation (555) of thalmelatine (314a), 6a,7-dehydrothalmelatine (474), C A, was only recently isolated as a natural product from Hernandia peltata. Identification was by comparison of spectral data with published values (549). [Pg.180]

The structure of fetidine (284) has been confirmed by mass spectroscopy.257 Examination of the mass spectra of the isomeric alkaloids thalicarpine and thal-melatine, dehydrothalicarpine and dehydrothalmelatine, and thalmetine and thalcimine (thalsimine) gave conclusive structural assignments on the basis of measurements of peak intensity for fragments containing the C=N function.258 O.r.d. studies of a series of bisbenzylisoquinoline alkaloids isolated from Thalictrum species have been recorded.259... [Pg.170]
