Methyl dihydrojasmonate 1 and magnolione 3 are of both academic and industrial interest. In this paper, we describe a flexible, high-yielding route to diastereomerically pure (+)-cis-(1R,2S)-methyl dihydrojasmonate 1 and the first synthesis of (+)-cis-(1R

Natural (+)-(1R,2S,3S)-methyl cucurbate (1b) and the (-)-δ-lactone of 3-epi-cucurbic acid (16) were synthesized from (+)-(1R,6S,7R)-bicyclonon-3-en-7-ol (5).Asymmetric hydrolysis of the acetate (8) of (+/-)-5 with pancreatin gave optically pure the
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.
