Chemistry and Stereochemistry of Iridoids, VI. - A Simple Method to Obtain (1S,2S,6R,7R)-(-)-2-(Benzylthio)-7-hydroxy-3-oxabicyclononan-9-one from Catalpol - Structure Determination by X-Ray Diffraction.

The isolation of catalpol (1) from Picrorhiza kurrooa (Scrophulariaceae) in a 100-g size is described.Catalpol (1) is converted into (1S,2S,6R,7R)-(-)-2-(benzylthio)-7-hydroxy-3-oxabicyclononan-9-one (4a) by a simple process.The structure of 4a, wh

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
