The absolute configuration of the pavine alkaloid (-)-argemonine (13 was firmly determined by chemical degradation,2 and through a non-empirical analysis of the cd spectrum. 3 The results of an empirical ord study were also interpreted as leading to the absolute configuration depicted. 4
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,
In this short review of several macrocyclic spermidine alkaloids, special consideration has been given to the correct determination of the absolute configuration at their chiral centers. The bases of interest are characterized by possessing a 13membered macrocyclic lactam ring incorporating spermidi
