  • Treatment of conjugated cyclodienes (5a-5c) with excess ozone in dichoromethane in the presence of added carbonyl compounds (3) resulted to give the corresponding diozonides 10 and cross-ozonides 14. Similarly, ozonolysis of the nonconjugated 1,4-cyclohexadiene (6a) and 1,5-cyclooctadiene (6b) under same conditions afforded both diozonides 20 and cross-ozonides 14. On the other hand, Ozonolysis of bicyclo[2.2.0]hepta-2,5-diene (6c) in the presence of 3A provided the corresponding diozonide 19.

  • Ozonolysis reactions of indene 5 in the presence of carbonyl compounds 6 provided the corresponding indenemonoozonide 9 and cross-ozonides 10a-c and 11a-c. Further reactions of ozonides 10 and 11 with the independently prepared carbonyl oxide 13 gave diozonides of structure 14a-c and 15a-c.

  • Ozonolysis reactions of cyclic olefins 1a-c and norbomene In in the presence of trifluoroactophenone 6 provided the corresponding cross-ozonides 7a-c and 7n. Further reactions of ozonides 7a-c and 7n with the independently prepared carbonyl oxide 11 gave diozonides of structure l0a-c and 10n. The ozonolysis of 1methylcyclopentene 12a and 1-methylcyclohexene 12b in the presence of trifluoroactophenone 6 provided exclusively ozonide 15 and 16 derived from capture of carbonyl oxide 13. All of the new ozonides have been isolated as pure substances and characterized by their 1H NMR and 13C NMR spectra.
