Jl. Ward et Mh. Beale, SYNTHESIS AND BIOLOGICAL-ACTIVITY OF STEREOCHEMICALLY LOCKED DERIVATIVES OF JASMONIC ACID, Journal of the Chemical Society. Perkin transactions. I, (20), 1993, pp. 2379-2381
Racemic 7-methyljasmonic acid 6 and 7-methyl-7-epi-jasmonic acid 7 hav
e been synthesised. Bioassay of these derivatives for induction of ten
dril coiling in Bryonia dioica demonstrated that the observed biologic
al activity of jasmonic acid is due to the minor 7-epi-isomer.
