The rhoeadine alkaloids are dextrorotatory bases found only in Papaver species (Papaveraceae); three typical examples being (+)-glaudine, (+)-epiglaudine and (+)-oreodine.2 The relative stereochemistry at C-l and C-2 was obtained from nmr coupling constants,

-Based on mass sptrometry, alkaloids of the rhoeadine type may be divided into acetals and scmiacetals. Each ties of compounds exhibits its own structurally &z&eristic fragmentation patt-THE alkaloids of rhoeadine type represent a new group of natural bases isolated from plants of Papaveraceae. Their general structure (I) is based on chemical and mass spectrometrical correlation with rhoeadine (Ia), the basic member of the group. Rhoeadine was earlier formulated as a modified benzylisoquinoline (II)'ma which was, II however, recently revised to Ia .* According to the substitution of the acetal group, the rhoeadine alkaloids may be divided into two groups: acetals (I, where % = Me) 1 F.
