Chemistry and Stereochemistry of Iridoids, V. - Crystal and Molecular Structure of Hexaacetylleonuride - Stereochemical Correlations of Some Iridoid Glucosides

Leonuride (ajugol, 1a) and myoporoside (2) are C-6 epimers, the configurations of which are specified differently in the literature.By X-ray structure analysis of hexaacetylleonuride (1d) the absolute configuration of leonuride (1a) is fixed, to which the configurations of catalpol (3a), antirrhinoside (6a), and harpagide (7a) as well as procumbide (14a) and 6-epi-harpagide (15a) are linked by chemical correlation.
