Criegee Intermediates Beyond Ozonolysis: Synthetic and …
In organic chemistry, ozonolysis is an organic reaction where the unsaturated bonds of alkenes (C=C), alkynes (C≡C), or azo compounds (N=N) are cleaved with ozone (O3). Alkenes and alkynes form organic compounds in which the multiple carbon–carbon bond has been replaced by a carbonyl (C=O) group while azo compounds form nitrosamines (N−N=O). The outcome of the reaction depends on the type of multiple bond being oxidized and the work-up conditions. Although the classic substrate for the Criegee oxidation are 1,2-diols, the oxidation can be employed with β-amino alcohols, α-hydroxy carbonyls, and α-keto acids, In the case of β-amino alcohols, a free radical mechanism is proposed. The Criegee oxidation can also be employed with 2,3-epoxy alcohols forms α- WebAlbert Eschenmoser, zweitgeborener Sohn aus Balgach im St. Galler Rheintal stammender Eltern, Alfons Otto Eschenmoser (1887–1977) [1] und Johanna, geb.
