Chemistry and Stereochemistry of Iridoids, XIII. - Synthesis of Enantiomerically Pure Methyl (1R,2S,2''Z)-(+)-Jasmonate Starting from Catalpol

Enantiomerically pure methyl (1R,2S,2''Z)(+)-jasmonate (2), which was recognized as a component of the fragrance of the jasmine flower oil, was synthesized starting from catalpol (3). 2 is easily epimerized to 1.Thus, it is necessary to use very mild conditions in the course of the synthesis and purification.These results raise the question whether 2 exists as a natural product in the flower of jasmine and 1 arises during the isolation.
