in the presence of trimethylsilyl trifluoromethanesulfonate as the catalyst. Application to cis - and trans -1,2-diols containing primary, secondary, and tertiary hydroxyl groups was examined, and a new rearrangement was found in the reaction of a d -glucono-1,5-lactone derivative having an acetyl group at O-6.
