Ozonolyses of cycloalkenes in the presence of carbonyl compounds

Ozonolysis reactions of a series of cyclic olefins 1 in the presence of carbonyl compounds 6 provided the corresponding cross-ozonides 42. Further reactions of ozonides 42 with the independently prepared carbonyl oxide +CH2-OO- gave diozonides of structure 43. All of the new ozonides have been isolated as pure substances and characterized by their 1H- and 13C- NMR spectra.

Cycloaddition between Carbonyl Oxides and Dicarbonyl Compounds: Isolation and Characterization of Novel Polycyclic 1,2,4,6-Tetroxepane Derivatives

Formaldehyde O-oxide reacts with dicarbonyl compounds to produce mono-ozonides formed by conventional cycloadditions to an aldehyde carbonyl group of the substrate, and/or polycyclic 1,2,4,6-tetroxepane derivatives arising from formal cycloadditions involving both carbonyl groups.Similar reactions between the more highly substituted carbonyl oxides, benzaldehyde and octanal O-oxides, and dicarbonyl compounds yielded the corresponding mono-ozonides as the sole isolable cycloaddition products.In certain favorable cases, mono-ozonides could undergo acid-catalysed intramolecular rearrangement to the corresponding 1,2,4,6-tetroxepanes.X-Ray crystallographic analyses of two 1,2,4,6-tetroxepanes, 6a and 13b, are recorded.
