Corinna Reisinger has constructed a brand new organocatalytic uneven epoxidation of cyclic and acyclic α,β-unsaturated ketones. during this thesis, Corinna files her method, utilizing fundamental amine salts as catalysts, and hydrogen peroxide as a cheap and environmentally benign oxidant. She describes the unheard of and robust catalytic uneven hydroperoxidation of α,β-enones, a technique which produces optically energetic 5-membered cyclic peroxyhemiketals in one operation. She additionally proves the flexibility and artificial price of the cyclic peroxyhemiketals via changing them into hugely enantioenriched acyclic and cyclic aldol items. at present, those cyclic aldol items are inaccessible by means of the other man made skill. in addition, cyclic peroxyhemiketals are precursors to optically energetic 1,2-dioxolanes that are of organic relevance. This paintings is a leap forward within the box of uneven epoxidation chemistry and descriptions the best approach within the literature for producing hugely enantioselective cyclic epoxyketones recognized to date.
