Oxidative ring cleavage of cyclic acetals with hypervalent tert-butylperoxy-lambda(3)-iodanes.
[reaction: see text] Exposure of cyclic acetals to 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one in the presence of tert-butyl hydroperoxide and potassium carbonate in benzene at room temperature results in oxidative ring cleavage to glycol monoesters via intermediate tert-butylperoxy ortho esters.
