Asymmetric catalysis by a chiral ruthenium porphyrin: Epoxidation, hydroxylation, and partial kinetic resolution of hydrocarbons

[GRAPHICS] A new member of our D-2 symmetry ruthenium porphyrins is shown to be a most selective catalyst for asymmetric epoxidation of terminal and trans-disubs tituted olefins. The same catalyst displays some selectivity in kinetic res olution of secondary alcohols and in what appears to be the first example o f catalytic enantioselective hydroxylation of tertiary alkanes.
