Diastereoselective Epoxidation of Hydroxy-containing Unsaturated Terpenes on Heterogeneous Titanium-catalyst

The diastereoselective epoxidation of substrates of interest as fine chemicals is here reported and the role of the OH-function in this reaction was studied particularly on non-allylic unsaturated terpenes. A heterogeneous system obtained grafting a titanocene precursor onto a commercial silica was used as catalyst.
