application of (13S,9Z,11E,15Z)-13-hydroxy(9,10,12,13,15, 16-2H6)octadeca-9,11,15-trienoic acid (D6-7) as a OH-functionalized precursor of δ-jasmin lactone allowed to gain insight into the stereochemical course of the biosynthesis to both enantiomers of this lactone. In this experiment, 88.3% of the metabolized labeled precursor was transformed under retention of the original configuration of the (R)-enantiomer
