Heterogenisation of ketone catalysts within mesoporous supports for asymmetric epoxidation

, 2013
The synthesis of the first mesoporous silica (150 Å) anchored carbohydrate-derived chiral ketone is described. This new heterogeneous catalyst has been shown to be effective in the asymmetric epoxidation of olefins by oxone.
