active area of research. While the existing methods serve well the need of synthetic organic chemistry, the yields of the reactions vary widely for different substrates and on many occasions they are abysmally low for multi-step reaction sequences. The work of Wipf et aL8 on the epoxidation of naphthoquinone spiroketals clearly demonstrates that the existing methods based on hydrogen peroxide may lead to

The stabilizing influence of neighboring group participation by the carbonyl group in concerted 1,2-acyl migration is related to the ability of the molecule to assume a transition stage geometry resembling a cyclopropyloxenium ion.
