✦ Synopsis


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
