Enantio- and diastereocontrolled synthesis of (-)-iridolactone and (+)-pedicularis-lactone.
[structure: see text]. Two iridoid lactones, (-)-iridolactone and (+)-pedicularis-lactone, have been synthesized in an enantio- and diastereocontrolled manner starting from a tricyclic chiral building block serving as a synthetic equivalent of chiral 3-(hydroxymethyl)cyclopenta-2,4-dien-1-ol.
