Chemistry and Stereochemistry of Iridoids, II. - About the Correlative Determination of the Configuration of Unedoside

Identical (5R,6R,8S,9S)-(-)-6,8-dihydroxy-1-oxoiridane (12) is prepared from both unedoside (4a) and catalpol (1) the absolute configuration of which is known.Thus, the absolute configuration of all centers of chirality of 4a is established except for C-1
