A stereoselective synthesis of ([plus-minus])-methyl jasmonate

, 1976
A short convergent synthesis of (+)-methyl jasmonate(l) is presented. The key step involves a nucleophilic B-alkylation, then an electrophilic a-alkylation on enone 6. The reaction is highly stereoselective and regioselective. Methyl dehydrojasmonate (7),

Optical Isomers of Methyl Jasmonate in Tea Aroma

Bioscience, Biotechnology, and Biochemistry, 1996
Two epimers of methyl jasmonate were optically resolved by capillary gas chromatography, using heptakis (2,3,6-tri-O-methyl)-β-cyclodextrin as the chiral stationary phase. In the tea volatile concentrates, both of these epimers were present as only one enantiomer, their absolute configurations being ascertained as (-)-(1R,2R)-methyl jasmonate and ...
