Ozonolyses of but-2-yne 1 in the presence of added carbonyl compounds
 3 afford α-oxo ozonides 4. Subsequent cycloadditions
 between ozonides 4 and cyclohexanone oxide 6, generated in situ
 by ozonolysis of O-methylcyclohexanone oxime, yield in turn
 α-diozonides 7 into which have been incorporated the
 carbon skeletons of all three substrates involved. Ozonolyses of
 acyloxy-substituted but-2-ynes 9 yield the corresponding bicyclic
 α-oxo ozonides 11 which subsequently participate in
 analogous cycloadditions with 6 to produce the corresponding
 α-diozonides 12. X-Ray crystallographic analysis of the
 crystalline diozonide 12a shows that it has been formed exclusively by
 exo-addition of 6 to 11a.
