The structures of fumaricine, fumaritine, and fumariline, minor alkaloids of F. officinalis, have been deduced by spectroscopic methods and by comparison with model systems. Nuclear Overhauser effects observed in these systems aided in the solution o

A chemical examination of Dicentra eximia has resulted in the isolation of six alkaloids. Protopine and dicentrine together constitute the greater portion of the total bases while d-glaucine was obtained in minute amounts. Two of the three other alka

The examination of the alkaloids of D. oregana has yielded seven bases, one of which appears to be identical with alkaloid δ previously found in two other Dicentra spp. A second base has not been adequately characterized because of paucity of materi

The Oppenauer oxidation of (±) ophiocarpine has been carried out to yield 3-(2′-vinyl-3′,4′-methylenedioxy) phenyl-4-hydroxyisoquinoline (2). Photolysis of this compound gave 3,4-dimethoxy-11,12-methylenedioxy-8,9-dihydro[1]benzoxepino(2,3-c)

Lobinaline, its derivatives, and its Hofmann degradation products have been examined by mass spectrometry and other spectral and chemical techniques. The results provide independent evidence for the structure of the alkaloid, but indicate that the fr
