A mild and straightforward epoxidation protocol based on sodium
perborate as primary oxidant and sodium dehydrocholate as organomediator
under homogeneous conditions is described. In particular, geraniol,
linalool, 3-carene, and α-pinene are quantitatively converted
into the corresponding 6,7-epoxides and trans-epoxides,
respectively. The bile acid salt is recovered from the reaction
mixture and may be reused with unchanged efficiency and selectivity.
