For studies on the cyclopentane ring formation from acyclic monoterpenes in the biosynthesis of iridoid glucosides, the following 13C-labeled precursors of the acyclic monoterpene series were synthesized : [9-13C]-and [4-13C]-10-hydroxygeraniol (9), [2-13C]-9, 10-dihydroxygeraniol (10), (R)-(+)-and (S)-(-)-[9-13C]-10-hydroxycitronellol ((R)-(+)-and (S)-(-)-8), (R)-(+)-and (S)-(-)-[8-13C]-9, 10-dihydroxycitronellol ((R)-(+)-and (S)-(-)-11).
