double bond in some terpene acetates was also selectively epoxidized 141 . The
catalyzed amine-oxide oxidation of 2-vinylnaphthalene was faster than the
stoichiometric oxidation using and thus Ru(TMP)(O)(amine
oxide) was considered a viable active intermediate; some data using
labeled water were interpreted in terms of a reaction pathway other than via

Some representative data showing the use of chiral Ru-porphyrins for
asymmetric epoxidation using amine oxides or PhIO as O-donors are given
in Table 1. The system 134 effects epoxidation with
5-88% yields and 28-77% ee values. Either or
