Abstract
Ozonolyses of vinyl ethers 1a-c in CH2Cl2 in the presence of allylic a nd homoallylic alcohols 3a-c give in each case the corresponding unsat urated hydroperoxy acetals 4a-h, derived from capture of the carbonyl oxides 2a-c by the unsaturated alcohols, N-Halogenosuccinimide-mediate d cyclisations of the hydroperoxides give the corresponding 1,2,4-trio xanes and/or 1,2,4-trioxepanes, depending on the structure of the hydr operoxides and the identity of the N-halogenosuccinimides.
