Chemistry and Stereochemistry of Iridoids, VII. - Enantiomerically Pure Intermediates for the Synthesis of Diastereomeric 12-epi-Prostaglandins

6,3'-epi-Catalpol (8a) is yielded from catalpol (7a) by a four component inversion reaction. 8a subsequently is converted into (1S,2S,6R,7S)-(-)-2-(benzylthio)-7-hydroxy-3-oxabicyclononan-9-on (4).LiAlH4 reduction of 4 affords the diastereomeric 2-
